Fix the issue #16

Removed global metadata cache and sync.Once
Each middleware instance now handles its own metadata initialization
Added tests to verify multiple instances work correctly
The changes ensure that:

Each route gets its own properly initialized middleware instance
Metadata is fetched and set correctly for each instance
No shared state between instances that could cause conflicts
Each instance can handle requests independently
The added test verifies this by creating multiple middleware instances with different routes and confirming they all initialize and function correctly. The test specifically checks that:

Each instance initializes successfully
Each instance gets its own metadata configuration
Each instance can handle requests independently
Callback URLs are correctly set per route

 * Using excluded URLs which do **NOT** require the OIDC authentication
 * Rate limiting requests to prevent the bruteforce attacks
 
+#### How to configure...
+
+##### Keeping secrets secret
+
+This works ONLY in kubernetes environments. Don't forget to create secret traefik-middleware-oidc with fields ISSUER, CLIENT_ID and SECRET keys.
+
+```
+apiVersion: traefik.io/v1alpha1
+kind: Middleware
+metadata:
+  name: oidc-with-open-urls
+  namespace: traefik
+spec:
+  plugin:
+    traefikoidc:

+        - /my-public-data
+```
+
+##### Excluded URLs with open access
+
+```

+        - /login # covers /login, /login/me, /login/reminder etc.
+        - /my-public-data
+```
+
+
+##### Allowed email domains
+
+Assuming that your OIDC provider allows anyone to log in, you may want to limit the access to people using emains in specific domain.
+
+```
+apiVersion: traefik.io/v1alpha1
+kind: Middleware
+metadata:
+  name: oidc-only-my-users
+  namespace: traefik
+spec:
+  plugin:

+        - email
+        - profile
+      allowedUserDomains:
+        - raczylo.com
+```
+
+
+##### Allowed groups and roles
+
+In case of multiple roles / groups and access separation for various endpoints you will need to create multiple traefik middlewares.
+Following example allows access for users who have additional role `guest-endpoints` assigned.
+
+```
+apiVersion: traefik.io/v1alpha1

+  name: oidc-guest-endpoints

+      callbackURL: /my-oidc/callback
+      logoutURL: /my-oidc/logout
+      scopes:
+        - openid
+        - email

-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output (only when using
-	  Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
-	* Dump style which prints with newlines, customizable indentation,
-	  and additional debug information such as types and all pointer addresses
-	  used to indirect to the final value
-	* A custom Formatter interface that integrates cleanly with the standard fmt
-	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
-	  similar to the default %v while providing the additional functionality
-	  outlined above and passing unsupported format verbs such as %x and %q
-	  along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew.  See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-	spew.Dump(myVar1, myVar2, ...)
-	spew.Fdump(someWriter, myVar1, myVar2, ...)
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type.  For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions.  This allows concurrent configuration
-options.  See the ConfigState documentation for more details.
-
-The following configuration options are available:
-	* Indent
-		String to use for each indentation level for Dump functions.
-		It is a single space by default.  A popular alternative is "\t".
-
-	* MaxDepth
-		Maximum number of levels to descend into nested data structures.
-		There is no limit by default.
-
-	* DisableMethods
-		Disables invocation of error and Stringer interface methods.
-		Method invocation is enabled by default.
-
-	* DisablePointerMethods
-		Disables invocation of error and Stringer interface methods on types
-		which only accept pointer receivers from non-pointer variables.
-		Pointer method invocation is enabled by default.
-
-	* DisablePointerAddresses
-		DisablePointerAddresses specifies whether to disable the printing of
-		pointer addresses. This is useful when diffing data structures in tests.
-
-	* DisableCapacities
-		DisableCapacities specifies whether to disable the printing of
-		capacities for arrays, slices, maps and channels. This is useful when
-		diffing data structures in tests.
-
-	* ContinueOnMethod
-		Enables recursion into types after invoking error and Stringer interface
-		methods. Recursion after method invocation is disabled by default.
-
-	* SortKeys
-		Specifies map keys should be sorted before being printed. Use
-		this to have a more deterministic, diffable output.  Note that
-		only native types (bool, int, uint, floats, uintptr and string)
-		and types which implement error or Stringer interfaces are
-		supported with other types sorted according to the
-		reflect.Value.String() output which guarantees display
-		stability.  Natural map order is used by default.
-
-	* SpewKeys
-		Specifies that, as a last resort attempt, map keys should be
-		spewed to strings and sorted by those strings.  This is only
-		considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
-	spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer.  For example, to dump to standard error:
-
-	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
-	(main.Foo) {
-	 unexportedField: (*main.Bar)(0xf84002e210)({
-	  flag: (main.Flag) flagTwo,
-	  data: (uintptr) <nil>
-	 }),
-	 ExportedField: (map[interface {}]interface {}) (len=1) {
-	  (string) (len=3) "one": (bool) true
-	 }
-	}
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
-	([]uint8) (len=32 cap=32) {
-	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
-	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
-	 00000020  31 32                                             |12|
-	}
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
-functions have syntax you are most likely already familiar with:
-
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Println(myVar, myVar2)
-	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output.  Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output
-
-The configuration options are controlled by an exported package global,
-spew.Config.  See ConfigState for options documentation.

-NewFormatter returns a custom formatter that satisfies the fmt.Formatter
-interface.  As a result, it integrates cleanly with standard fmt package
-printing functions.  The formatter is useful for inline printing of smaller data
-types similar to the standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Typically this function shouldn't be called directly.  It is much easier to make
-use of the custom formatter by calling one of the convenience functions such as
-Printf, Println, or Fprintf.

-// SequenceMatcher compares sequence of strings. The basic
-// algorithm predates, and is a little fancier than, an algorithm
-// published in the late 1980's by Ratcliff and Obershelp under the
-// hyperbolic name "gestalt pattern matching".  The basic idea is to find
-// the longest contiguous matching subsequence that contains no "junk"
-// elements (R-O doesn't address junk).  The same idea is then applied
-// recursively to the pieces of the sequences to the left and to the right
-// of the matching subsequence.  This does not yield minimal edit
-// sequences, but does tend to yield matches that "look right" to people.
-//
-// SequenceMatcher tries to compute a "human-friendly diff" between two
-// sequences.  Unlike e.g. UNIX(tm) diff, the fundamental notion is the
-// longest *contiguous* & junk-free matching subsequence.  That's what
-// catches peoples' eyes.  The Windows(tm) windiff has another interesting
-// notion, pairing up elements that appear uniquely in each sequence.
-// That, and the method here, appear to yield more intuitive difference
-// reports than does diff.  This method appears to be the least vulnerable
-// to synching up on blocks of "junk lines", though (like blank lines in
-// ordinary text files, or maybe "<P>" lines in HTML files).  That may be
-// because this is the only method of the 3 that has a *concept* of
-// "junk" <wink>.
-//
-// Timing:  Basic R-O is cubic time worst case and quadratic time expected
-// case.  SequenceMatcher is quadratic time for the worst case and has
-// expected-case behavior dependent in a complicated way on how many
-// elements the sequences have in common; best case time is linear.

-Objx - Go package for dealing with maps, slices, JSON and other data.
-
-Get started:
-
-- Install Objx with [one line of code](#installation), or [update it with another](#staying-up-to-date)
-- Check out the API Documentation http://pkg.go.dev/github.com/stretchr/objx
-
-## Overview
-Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes a powerful `Get` method (among others) that allows you to easily and quickly get access to data within the map, without having to worry too much about type assertions, missing data, default values etc.
-
-### Pattern
-Objx uses a predictable pattern to make access data from within `map[string]interface{}` easy. Call one of the `objx.` functions to create your `objx.Map` to get going:
-
-    m, err := objx.FromJSON(json)
-
-NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong, the rest will be optimistic and try to figure things out without panicking.
-
-Use `Get` to access the value you're interested in.  You can use dot and array
-notation too:
-
-     m.Get("places[0].latlng")
-
-Once you have sought the `Value` you're interested in, you can use the `Is*` methods to determine its type.
-
-     if m.Get("code").IsStr() { // Your code... }
-
-Or you can just assume the type, and use one of the strong type methods to extract the real value:
-
-    m.Get("code").Int()
-
-If there's no value there (or if it's the wrong type) then a default value will be returned, or you can be explicit about the default value.
-
-     Get("code").Int(-1)
-
-If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating, manipulating and selecting that data.  You can find out more by exploring the index below.
-
-### Reading data
-A simple example of how to use Objx:
-
-    // Use MustFromJSON to make an objx.Map from some JSON
-    m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
-
-    // Get the details
-    name := m.Get("name").Str()
-    age := m.Get("age").Int()
-
-    // Get their nickname (or use their name if they don't have one)
-    nickname := m.Get("nickname").Str(name)
-
-### Ranging
-Since `objx.Map` is a `map[string]interface{}` you can treat it as such.  For example, to `range` the data, do what you would expect:
-
-    m := objx.MustFromJSON(json)
-    for key, value := range m {
-      // Your code...
-    }
-
-## Installation
-To install Objx, use go get:
-
-    go get github.com/stretchr/objx
-
-### Staying up to date
-To update Objx to the latest version, run:
-
-    go get -u github.com/stretchr/objx
-
-### Supported go versions
-We currently support the three recent major Go versions.

-Package objx provides utilities for dealing with maps, slices, JSON and other data.
-
-# Overview
-
-Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
-a powerful `Get` method (among others) that allows you to easily and quickly get
-access to data within the map, without having to worry too much about type assertions,
-missing data, default values etc.
-
-# Pattern
-
-Objx uses a predictable pattern to make access data from within `map[string]interface{}` easy.
-Call one of the `objx.` functions to create your `objx.Map` to get going:
-
-	m, err := objx.FromJSON(json)
-
-NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
-the rest will be optimistic and try to figure things out without panicking.
-
-Use `Get` to access the value you're interested in.  You can use dot and array
-notation too:
-
-	m.Get("places[0].latlng")
-
-Once you have sought the `Value` you're interested in, you can use the `Is*` methods to determine its type.
-
-	if m.Get("code").IsStr() { // Your code... }
-
-Or you can just assume the type, and use one of the strong type methods to extract the real value:
-
-	m.Get("code").Int()
-
-If there's no value there (or if it's the wrong type) then a default value will be returned,
-or you can be explicit about the default value.
-
-	Get("code").Int(-1)
-
-If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating,
-manipulating and selecting that data.  You can find out more by exploring the index below.
-
-# Reading data
-
-A simple example of how to use Objx:
-
-	// Use MustFromJSON to make an objx.Map from some JSON
-	m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
-
-	// Get the details
-	name := m.Get("name").Str()
-	age := m.Get("age").Int()
-
-	// Get their nickname (or use their name if they don't have one)
-	nickname := m.Get("nickname").Str(name)
-
-# Ranging
-
-Since `objx.Map` is a `map[string]interface{}` you can treat it as such.
-For example, to `range` the data, do what you would expect:
-
-	m := objx.MustFromJSON(json)
-	for key, value := range m {
-	  // Your code...
-	}

-// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
-//
-// # Example Usage
-//
-// The following is a complete example using assert in a standard test function:
-//
-//	import (
-//	  "testing"
-//	  "github.com/stretchr/testify/assert"
-//	)
-//
-//	func TestSomething(t *testing.T) {
-//
-//	  var a string = "Hello"
-//	  var b string = "Hello"
-//
-//	  assert.Equal(t, a, b, "The two words should be the same.")
-//
-//	}
-//
-// if you assert many times, use the format below:
-//
-//	import (
-//	  "testing"
-//	  "github.com/stretchr/testify/assert"
-//	)
-//
-//	func TestSomething(t *testing.T) {

-//	  var b string = "Hello"
-//
-//	  assert.Equal(a, b, "The two words should be the same.")
-//	}
-//
-// # Assertions

-// Package mock provides a system by which it is possible to mock your objects
-// and verify calls are happening as expected.
-//
-// # Example Usage
-//
-// The mock package provides an object, Mock, that tracks activity on another object.  It is usually
-// embedded into a test object as shown below:
-//
-//	type MyTestObject struct {
-//	  // add a Mock object instance
-//	  mock.Mock
-//
-//	  // other fields go here as normal
-//	}
-//
-// When implementing the methods of an interface, you wire your functions up
-// to call the Mock.Called(args...) method, and return the appropriate values.
-//
-// For example, to mock a method that saves the name and age of a person and returns
-// the year of their birth or an error, you might write this:
-//
-//	func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
-//	  args := o.Called(firstname, lastname, age)
-//	  return args.Int(0), args.Error(1)
-//	}
-//
-// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
-// index position. Given this argument list:
-//
-//	(12, true, "Something")
-//
-// You could read them out strongly typed like this:
-//
-//	args.Int(0)
-//	args.Bool(1)
-//	args.String(2)
-//
-// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
-//
-//	return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
-//
-// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
-// cases you should check for nil first.

-// or individual tests (depending on which interface(s) you
-// implement).
-//
-// A testing suite is usually built by first extending the built-in
-// suite functionality from suite.Suite in testify.  Alternatively,
-// you could reproduce that logic on your own if you wanted (you
-// just need to implement the TestingSuite interface from
-// suite/interfaces.go).
-//
-// After that, you can implement any of the interfaces in
-// suite/interfaces.go to add setup/teardown functionality to your
-// suite, and add any methods that start with "Test" to add tests.
-// Methods that do not match any suite interfaces and do not begin
-// with "Test" will not be run by testify, and can safely be used as
-// helper methods.
-//
-// Once you've built your testing suite, you need to run the suite

-# YAML support for the Go language
-
-Introduction
-------------
-
-The yaml package enables Go programs to comfortably encode and decode YAML
-values. It was developed within [Canonical](https://www.canonical.com) as
-part of the [juju](https://juju.ubuntu.com) project, and is based on a
-pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
-C library to parse and generate YAML data quickly and reliably.
-
-Compatibility
--------------
-
-The yaml package supports most of YAML 1.2, but preserves some behavior
-from 1.1 for backwards compatibility.
-
-Specifically, as of v3 of the yaml package:
-
- - YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being
-   decoded into a typed bool value. Otherwise they behave as a string. Booleans
-   in YAML 1.2 are _true/false_ only.
- - Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_
-   as specified in YAML 1.2, because most parsers still use the old format.
-   Octals in the  _0o777_ format are supported though, so new files work.
- - Does not support base-60 floats. These are gone from YAML 1.2, and were
-   actually never supported by this package as it's clearly a poor choice.
-
-and offers backwards
-compatibility with YAML 1.1 in some cases.
-1.2, including support for
-anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
-implemented, and base-60 floats from YAML 1.1 are purposefully not
-supported since they're a poor design and are gone in YAML 1.2.
-
-Installation and usage
-----------------------
-
-The import path for the package is *gopkg.in/yaml.v3*.
-
-To install it, run:
-
-    go get gopkg.in/yaml.v3
-
-API documentation
------------------
-
-If opened in a browser, the import path itself leads to the API documentation:
-
-  - [https://gopkg.in/yaml.v3](https://gopkg.in/yaml.v3)
-
-API stability
--------------
-
-The package API for yaml v3 will remain stable as described in [gopkg.in](https://gopkg.in).
-
-
-License
--------
-
-The yaml package is licensed under the MIT and Apache License 2.0 licenses.
-Please see the LICENSE file for details.
-
-
-Example
--------
-
-```Go
-package main
-
-import (
-        "fmt"
-        "log"
-
-        "gopkg.in/yaml.v3"
-)
-
-var data = `
-a: Easy!
-b:
-  c: 2
-  d: [3, 4]
-`
-
-// Note: struct fields must be public in order for unmarshal to
-// correctly populate the data.
-type T struct {
-        A string
-        B struct {
-                RenamedC int   `yaml:"c"`
-                D        []int `yaml:",flow"`
-        }
-}
-
-func main() {
-        t := T{}
-    
-        err := yaml.Unmarshal([]byte(data), &t)
-        if err != nil {
-                log.Fatalf("error: %v", err)
-        }
-        fmt.Printf("--- t:\n%v\n\n", t)
-    
-        d, err := yaml.Marshal(&t)
-        if err != nil {
-                log.Fatalf("error: %v", err)
-        }
-        fmt.Printf("--- t dump:\n%s\n\n", string(d))
-    
-        m := make(map[interface{}]interface{})
-    
-        err = yaml.Unmarshal([]byte(data), &m)
-        if err != nil {
-                log.Fatalf("error: %v", err)
-        }
-        fmt.Printf("--- m:\n%v\n\n", m)
-    
-        d, err = yaml.Marshal(&m)
-        if err != nil {
-                log.Fatalf("error: %v", err)
-        }
-        fmt.Printf("--- m dump:\n%s\n\n", string(d))
-}
-```
-
-This example will generate the following output:
-
-```
---- t:
-{Easy! {2 [3 4]}}
-
---- t dump:
-a: Easy!
-b:
-  c: 2
-  d: [3, 4]
-
-
---- m:
-map[a:Easy! b:map[c:2 d:[3 4]]]
-
---- m dump:
-a: Easy!
-b:
-  c: 2
-  d:
-  - 3
-  - 4
-```
