 # Concepts
 
-Everything You Need to Know
-{: .subtitle }
+This page explains the base concepts of Traefik.
+
+---
+
+## Introduction
+
+Traefik is based on the concept of EntryPoints, Routers, Middlewares and Services.
+
+The main features include dynamic configuration, automatic service discovery, and support for multiple backends and protocols.
+
+1. [EntryPoints](../routing/entrypoints.md "Link to docs about EntryPoints"): EntryPoints are the network entry points into Traefik. They define the port which will receive the packets, and whether to listen for TCP or UDP.
+
+2. [Routers](../routing/routers/index.md "Link to docs about routers"): A router is in charge of connecting incoming requests to the services that can handle them.
+
+3. [Middlewares](../middlewares/overview.md "Link to docs about middlewares"): Attached to the routers, middlewares can modify the requests or responses before they are sent to your service
+
+4. [Services](../routing/services/index.md "Link to docs about services"): Services are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
 
 ## Edge Router
 
-Traefik is an _Edge Router_, it means that it's the door to your platform, and that it intercepts and routes every incoming request:
-it knows all the logic and every rule that determine which services handle which requests (based on the [path](../routing/routers/index.md#rule), the [host](../routing/routers/index.md#rule), [headers](../routing/routers/index.md#rule), [and so on](../routing/routers/index.md#rule) ...).

+## How Traefik is Storing and Serving TLS Certificates?
+
+### Storing TLS Certificates
+
+[TLS](../https/tls.md "Link to Traefik TLS docs") certificates are either provided directly by the [dynamic configuration](./configuration-overview.md#the-dynamic-configuration "Link to dynamic configuration overview") from [providers](../https/tls.md#user-defined "Link to the TLS configuration"),
+or by [ACME resolvers](../https/acme.md#providers "Link to ACME resolvers"), which act themselves as providers internally.
+
+For each TLS certificate, Traefik produces an identifier used as a key to store it.
+This identifier is constructed as the alphabetically ordered concatenation of the SANs `DNSNames` and `IPAddresses` of the TLScertificate.
+
+#### Examples:
+
+| X509v3 Subject Alternative Name         | TLS Certificate Identifier  |
+|-----------------------------------------|-----------------------------|
+| `DNS:example.com, IP Address:127.0.0.1` | `127.0.0.1,example.com`     |
+| `DNS:example.com, DNS:*.example.com`    | `*.example.com,example.com` |
+
+The identifier is used to store TLS certificates in order to be later used to handle TLS connections.
+This operation happens each time there are configuration changes.
+
+If multiple TLS certificates are provided with the same SANs definition (same identifier), only the one processed first is kept.
+Because the dynamic configuration is aggregated from all providers,
+when processing it to gather TLS certificates,
+there is no guarantee of the order in which they would be processed.
+This means that along with configurations applied, it is possible that the TLS certificate retained for a given identifier differs.
+
+### Serving TLS Certificates
+
+For each incoming connection, Traefik is serving the "best" matching TLS certificate for the provided server name.
+
+The TLS certificate selection process narrows down the list of TLS certificates matching the server name,
+and then selects the last TLS certificate in this list after having ordered it by the identifier alphabetically.
+
+#### Examples:
+
+| Selected TLS Certificates Identifiers               | Sorted TLS Certificates Identifiers                 | Served Certificate Identifier |
+|-----------------------------------------------------|-----------------------------------------------------|-------------------------------|
+| `127.0.0.1,example.com`,`*.example.com,example.com` | `*.example.com,example.com`,`127.0.0.1,example.com` | `127.0.0.1,example.com`       |
+| `*.example.com,example.com`,`example.com`           | `*.example.com,example.com`,`example.com`           | `example.com`                 |
+
+### Caching TLS Certificates
+
+While Traefik is serving the best matching TLS certificate for each incoming connection,
+the selection process cost for each incoming connection is avoided thanks to a cache mechanism.
+
+Once a TLS certificate has been selected as the "best" TLS certificate for a server name,
+it is cached for an hour, avoiding the selection process for further connections.
+
+Nonetheless, when a new configuration is applied, the cache is reset.

+
+If you're trying to renew wildcard certificates, with DNS challenge,

-# SPIFFE
-
-Secure the backend connection with SPIFFE.
-{: .subtitle }
-
-[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
-provides a secure identity in the form of a specially crafted X.509 certificate, 
-to every workload in an environment.
-
-Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
-
-## Configuration
-
-### General
-
-Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
-It can be defined by using a file (YAML or TOML) or CLI arguments.
-
-### Workload API
-
-The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
-
-!!! info "Enabling SPIFFE in ServersTransports"
-
-    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
-    Each [ServersTransport](../routing/services/index.md#serverstransport_1) that is meant to be secured with SPIFFE must [explicitly](../routing/services/index.md#spiffe) enable it.
-
-!!! warning "SPIFFE can cause Traefik to stall"
-	When using SPIFFE,
-	Traefik will wait for the first SVID to be delivered before starting.
-	If Traefik is hanging when waiting on SPIFFE SVID delivery,
-	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

-# Tailscale
-
-Provision TLS certificates for your internal Tailscale services.
-{: .subtitle }
-
-To protect a service with TLS, a certificate from a public Certificate Authority is needed.
-In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
-
-## Certificate resolvers
-
-To obtain a TLS certificate from the Tailscale daemon,
-a Tailscale certificate resolver needs to be configured as below.
-
-!!! info "Referencing a certificate resolver"
-
-    Defining a certificate resolver does not imply that routers are going to use it automatically.
-    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.
-
-```yaml tab="File (YAML)"
-certificatesResolvers:
-    myresolver:
-        tailscale: {}
-```
-
-```toml tab="File (TOML)"
-[certificatesResolvers.myresolver.tailscale]
-```
-
-```bash tab="CLI"
---certificatesresolvers.myresolver.tailscale=true
-```
-
-## Domain Definition
-
-A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
-
-- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
-  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
-
-- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
-  in the [router's rule](../routing/routers/index.md#rule).
-
-!!! info "Tailscale Domain Format"
-
-    The domain is only taken into account if it is a Tailscale-specific one,
-    i.e. of the form `machine-name.domains-alias.ts.net`.
-

 Handling Content-Type auto-detection
 {: .subtitle }
 
-The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
-when it is not set by the backend.
+The Content-Type middleware - or rather its `autoDetect` option -
+specifies whether to let the `Content-Type` header,
+if it has not been defined by the backend,
+be automatically set to a value derived from the contents of the response.
+
+As a proxy, the default behavior should be to leave the header alone,
+regardless of what the backend did with it.
+However, the historic default was to always auto-detect and set the header if it was not already defined,
+and altering this behavior would be a breaking change which would impact many users.
+
+This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
 
 !!! info
 
+    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
+    is still to automatically set the `Content-Type` header.
+    Therefore, given the default value of the `autoDetect` option (false),
+    simply enabling this middleware for a router switches the router's behavior.
+
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

-# Migration Guide: From v2 to v3
-
-How to Migrate from Traefik v2 to Traefik v3.
-{: .subtitle }
-
-The version 3 of Traefik introduces a number of breaking changes,
-which require one to update their configuration when they migrate from v2 to v3.
-The goal of this page is to recapitulate all of these changes, and in particular to give examples,
-feature by feature, of how the configuration looked like in v2, and how it now looks like in v3.
-
-## IPWhiteList
-
-In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
-
-## gRPC Metrics
-
-In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.  
-
-## Deprecated Options Removal
-
-- The `pilot` option has been removed from the static configuration.
-- The `tracing.datadog.globaltag` option has been removed.
-- The `namespace` option of Consul, Consul Catalog and Nomad providers has been removed.
-- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Marathon, Consul Catalog, and Docker providers.
-- `sslRedirect`, `sslTemporaryRedirect`, `sslHost`, `sslForceHost` and `featurePolicy` options of the Headers middleware have been removed.
-- The `forceSlash` option of the StripPrefix middleware has been removed.
-- the `preferServerCipherSuites` option has been removed.
-
-## Matchers
-
-In v3, the `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
-
-`QueryRegexp` has been introduced to match query values using a regular expression.
-
-`HeaderRegexp`, `HostRegexp`, `PathRegexp`, `QueryRegexp`, and `HostSNIRegexp` matchers now uses the [Go regexp syntax](https://golang.org/pkg/regexp/syntax/).
-
-All matchers now take a single value (except `Headers`, `HeaderRegexp`, `Query`, and `QueryRegexp` which take two)
-and should be explicitly combined using logical operators to mimic previous behavior.
-
-`Query` can take a single value to match is the query value that has no value (e.g. `/search?mobile`).
-
-`HostHeader` has been removed, use `Host` instead.
-
-## Content-Type Auto-Detection
-
-In v3, the `Content-Type` header is not auto-detected anymore when it is not set by the backend.
-One should use the `ContentType` middleware to enable the `Content-Type` header value auto-detection.

 ### Nomad Namespace
 
 In `v2.10`, the `namespace` option of the Nomad provider is deprecated, please use the `namespaces` options instead.
+
+### Kubernetes CRDs
+
+In `v2.10`, the Kubernetes CRDs API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.
+
+As the Kubernetes CRD provider still works with both API Versions (`traefik.io/v1alpha1` and `traefik.containo.us/v1alpha1`),
+it means that for the same kind, namespace and name, the provider will only keep the `traefik.io/v1alpha1` resource.
+
+In addition, the Kubernetes CRDs API Version `traefik.io/v1alpha1` will not be supported in Traefik v3 itself.
+
+Please note that it is a requirement to update the CRDs and the RBAC in the cluster before upgrading Traefik.
+To do so, please apply the required [CRDs](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml) and [RBAC](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-rbac.yml) manifests for v2.10:
