+# Maintainer's Guidelines
+
+![Maintainer's Guidelines](../assets/img/maintainers-guidelines.png)
+
+Note: the document is a work in progress.
+
+Welcome to the Traefik Community.
+This document describes how to be part of the core team
+as well as various responsibilities
+and guidelines for Traefik maintainers.
+We are strongly promoting a philosophy of openness and sharing,
+and firmly standing against the elitist closed approach.
+Being part of the core team should be accessible to anyone motivated
+and wants to be part of that journey!
+
+## Onboarding Process
+
+If you consider joining our community please drop us a line using Twitter or leave a note in the issue.
+We will schedule a quick call to meet you and learn more about your motivation.
+During the call, the team will discuss the process of becoming a maintainer.
+We will be happy to answer any questions and explain all your doubts.
+
+## Maintainer's Requirements
+
+Note: you do not have to meet all the listed requirements,
+but must have achieved several.
+
+- Enabled [2FA](https://docs.github.com/en/github/authenticating-to-github/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication) on your Github account
+- The contributor has opened and successfully run medium to large PR’s in the past 6 months.
+- The contributor has participated in multiple code reviews of other PR’s,
+  including those of other maintainers and contributors.
+- The contributor showed a consistent pattern of helpful, non-threatening, and friendly behavior towards other community members in the past.
+- The contributor is active on Traefik Community forums
+  or other technical forums/boards such as K8S slack, Reddit, StackOverflow, hacker news.
+- Have read and accepted the contributor guidelines.
+
+## Maintainer's Responsibilities and Privileges
+
+There are lots of areas where you can contribute to the project,
+but we can suggest you start with activities such as:
+
+- PR reviewing.
+    - According to our guidelines we require you have at least 3 reviewers,
+      thus you can review a PR and leave the relevant comment if it is necessary.
+- Participating in a daily [issue triage](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md).
+    - The process helps to understand and prioritize the reported issue according to its importance and severity.
+      This is crucial to learn how our users implement Traefik.
+      Each of the issues that are labeled as bug/possible bug/confirmed requires a reproducible use case. 
+      You can help in creating a reproducible use case if it has not been added to the issue
+      or use the sample code provided by the reporter.
+      Typically, a simple docker compose should be enough to reproduce the issue.
+- Code contribution.
+- Documentation contribution.
+    - Technical documentation is one of the most important components of the product.
+      The ability to set up a testing environment in a few minutes,
+      using the official documentation,
+      is a game changer.
+- You will be listed on our Maintainers Github page
+  as well as on our website in the section [maintainers](maintainers.md).
+- We will be promoting you on social channels (mostly on Twitter).
+
+## Governance
+
+- Roadmap meetings on a regular basis where all maintainers are welcome.
+
+## Communicating
+
+- All of our maintainers are added to Slack #traefik-maintainers channel that belongs to Traefik labs workspace.
+  Having the team in one place helps us to communicate effectively. 
+  You can reach Traefik core developers directly,
+  which offers the possibility to discuss issues, pull requests, enhancements more efficiently
+  and get the feedback almost immediately.
+  Fewer blockers mean more fun and engaging work.
+
+- On a daily basis, we publish a report that includes all the activities performed during the day.
+  You are updated in regard to the workload that has been processed including:
+  working on the new features and enhancements,
+  activities related to the reported issues and PR’s,
+  other important project-related announcements.
+
+- At 5:00 PM CET every day we review all the created issues that have been reported,
+  assign them the appropriate *[labels](maintainers.md#labels)*
+  and prioritize them based on the severity of the problem.
+  The process is called *[issue triaging](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md)*.
+  Each of the maintainers is welcome to join the meeting.
+  For that purpose, we use a dedicated Discord server
+  where you are invited once you have become the official maintainer.
+
+## Maintainers Activity
+
+In order to keep the core team efficient and dynamic,
+maintainers' activity and involvement will be reviewed on a regular basis.
+
+- Has the maintainer engaged with the team and the community by meeting two or more of these benchmarks in the past six months?
+    - Has the maintainer participated in at least two or three maintainer meetings?
+    - Substantial review of at least one or two PRs from either contributors or maintainers.
+    - Opened at least one or two bug fixes or feature request PRs
+      that were eventually merged (or on a trajectory for merge).
+    - Substantial participation in the Help Wanted program (answered questions, helped identify issues, applied guidelines from the Help Wanted guide to open issues).
+    - Substantial participation with the community in general.
+
+- Has the maintainer shown a consistent pattern of helpful,
+  non-threatening,
+  and friendly behavior towards other people on the maintainer team and with our community?
+
+## Additional Comments for (not only) Maintainers
+
+- Be able to put yourself in users’ shoes.
+- Be open-minded and respectful with other maintainers and other community members.
+- Keep the communication public - 
+  if anyone tries to communicate with you directly,
+  ask him politely to move the conversation to a public communication channel.
+- Stay away from defensive comments.
+- Please try to express your thoughts clearly enough
+  and note that some of us are not native English speakers.
+  Try to rephrase your sentences, avoiding mental shortcuts;
+  none of us is able to predict your thoughts.
+- There are a lot of use cases of using Traefik
+  and even more issues that are difficult to reproduce.
+  If the issue can’t be replicated due to a lack of reproducible case (a simple docker compose should be enough) - 
+  set your time limits while working on the issue
+  and express clearly that you were not able to replicate it.
+  You can come back later to that case.
+- Be proactive.
+- Emoji are fine,
+  but if you express yourself clearly enough they are not necessary.
+  They will not replace good communication.
+- Embrace mentorship.
+- Keep in mind that we all have the same intent to improve the project.

+# FAQ
+
+## Why is Traefik Answering `XXX` HTTP Response Status Code?
+
+Traefik is a dynamic reverse proxy,
+and while the documentation often demonstrates configuration options through file examples,
+the core feature of Traefik is its dynamic configurability,
+directly reacting to changes from providers over time.
+
+Notably, a part of the configuration is [static](../configuration-overview/#the-static-configuration),
+and can be provided by a file on startup, whereas various providers,
+such as the file provider,
+contribute dynamically all along the traefik instance lifetime to its [dynamic configuration](../configuration-overview/#the-dynamic-configuration) changes.
+
+In addition, the configuration englobes concepts such as the EntryPoint which can be seen as a listener on the Transport Layer (TCP),
+as apposed to the Router which is more about the Presentation (TLS) and Application layers (HTTP).
+And there can be as many routers as one wishes for a given EntryPoint.
+
+In other words, for a given Entrypoint,
+at any given time the traffic seen is not bound to be just about one protocol.
+It could be HTTP, or otherwise. Over TLS, or not.
+Not to mention that dynamic configuration changes potentially make that kind of traffic vary over time.
+
+Therefore, in this dynamic context,
+the static configuration of an `entryPoint` does not give any hint whatsoever about how the traffic going through that `entryPoint` is going to be routed.
+Or whether it's even going to be routed at all,
+i.e. whether there is a Router matching the kind of traffic going through it.
+
+### `404 Not found`
+
+Traefik returns a `404` response code in the following situations:
+
+- A request reaching an EntryPoint that has no Routers
+- An HTTP request reaching an EntryPoint that has no HTTP Router
+- An HTTPS request reaching an EntryPoint that has no HTTPS Router
+- A request reaching an EntryPoint that has HTTP/HTTPS Routers that cannot be matched
+
+From Traefik's point of view,
+every time a request cannot be matched with a router the correct response code is a `404 Not found`.
+
+In this situation, the response code is not a `503 Service Unavailable`
+because Traefik is not able to confirm that the lack of a matching router for a request is only temporary.
+Traefik's routing configuration is dynamic and aggregated from different providers,
+hence it's not possible to assume at any moment that a specific route should be handled or not.
+
+??? info "This behavior is consistent with rfc7231"
+
+    ```txt
+    The server is currently unable to handle the request due to a
+    temporary overloading or maintenance of the server. The implication
+    is that this is a temporary condition which will be alleviated after
+    some delay. If known, the length of the delay MAY be indicated in a
+    Retry-After header. If no Retry-After is given, the client SHOULD
+    handle the response as it would for a 500 response.
+
+        Note: The existence of the 503 status code does not imply that a
+        server must use it when becoming overloaded. Some servers may wish
+        to simply refuse the connection.
+    ```
+
+    Extract from [rfc7231#section-6.6.4](https://datatracker.ietf.org/doc/html/rfc7231#section-6.6.4).
+
+### `502 Bad Gateway`
+
+Traefik returns a `502` response code when an error happens while contacting the upstream service.
+
+### `503 Service Unavailable`
+
+Traefik returns a `503` response code when a Router has been matched
+but there are no servers ready to handle the request.
+
+This situation is encountered when a service has been explicitly configured without servers,
+or when a service has healthcheck enabled and all servers are unhealthy.
+
+### `XXX` Instead of `404`
+
+Sometimes, the `404` response code doesn't play well with other parties or services (such as CDNs).
+
+In these situations, you may want Traefik to always reply with a `503` response code,
+instead of a `404` response code.
+
+To achieve this behavior, a simple catchall router,
+with the lowest possible priority and routing to a service without servers,
+can handle all the requests when no other router has been matched.
+
+The example below is a file provider only version (`yaml`) of what this configuration could look like:
+
+```yaml tab="Static configuration"
+# traefik.yml
+
+entrypoints:
+  web:
+    address: :80
+
+providers:
+  file:
+    filename: dynamic.yaml
+```
+
+```yaml tab="Dynamic configuration"
+# dynamic.yaml
+
+http:
+  routers:
+    catchall:
+      # attached only to web entryPoint
+      entryPoints:
+        - "web"
+      # catchall rule
+      rule: "PathPrefix(`/`)"
+      service: unavailable
+      # lowest possible priority
+      # evaluated when no other router is matched
+      priority: 1
+
+  services:
+    # Service that will always answer a 503 Service Unavailable response
+    unavailable:
+      loadBalancer:
+        servers: {}
+```
+
+!!! info "Dedicated service"
+    If there is a need for a response code other than a `503` and/or a custom message,
+    the principle of the above example above (a catchall router) still stands,
+    but the `unavailable` service should be adapted to fit such a need.
+
+## Why Is My TLS Certificate Not Reloaded When Its Contents Change ? 
+
+With the file provider,
+a configuration update is only triggered when one of the [watched](../providers/file.md#provider-configuration) configuration files is modified.
+
+Which is why, when a certificate is defined by path,
+and the actual contents of this certificate change,
+a configuration update is _not_ triggered.
+
+To take into account the new certificate contents, the update of the dynamic configuration must be forced.
+One way to achieve that, is to trigger a file notification,
+for example, by using the `touch` command on the configuration file.

 ##### `ipStrategy.excludedIPs`
 
+!!! important "Contrary to what the name might suggest, this option is _not_ about excluding an IP from the rate limiter, and therefore cannot be used to deactivate rate limiting for some IPs."
+
+!!! important "If `depth` is specified, `excludedIPs` is ignored."
+
+`excludedIPs` is meant to address two classes of somewhat distinct use-cases:
+
+1. Distinguish IPs which are behind the same (set of) reverse-proxies so that each of them contributes, independently to the others,
+   to its own rate-limit "bucket" (cf the [leaky bucket analogy](https://wikipedia.org/wiki/Leaky_bucket)).
+   In this case, `excludedIPs` should be set to match the list of `X-Forwarded-For IPs` that are to be excluded,
+   in order to find the actual clientIP.
+
+    !!! example "Each IP as a distinct source"
+
+        | X-Forwarded-For                | excludedIPs           | clientIP     |
+        |--------------------------------|-----------------------|--------------|
+        | `"10.0.0.1,11.0.0.1,12.0.0.1"` | `"11.0.0.1,12.0.0.1"` | `"10.0.0.1"` |
+        | `"10.0.0.2,11.0.0.1,12.0.0.1"` | `"11.0.0.1,12.0.0.1"` | `"10.0.0.2"` |
+
+2. Group together a set of IPs (also behind a common set of reverse-proxies) so that they are considered the same source,
+   and all contribute to the same rate-limit bucket.
+
+    !!! example "Group IPs together as same source"
+
+        |  X-Forwarded-For               |  excludedIPs | clientIP     |
+        |--------------------------------|--------------|--------------|
+        | `"10.0.0.1,11.0.0.1,12.0.0.1"` | `"12.0.0.1"` | `"11.0.0.1"` |
+        | `"10.0.0.2,11.0.0.1,12.0.0.1"` | `"12.0.0.1"` | `"11.0.0.1"` |
+        | `"10.0.0.3,11.0.0.1,12.0.0.1"` | `"12.0.0.1"` | `"11.0.0.1"` |
+
+For completeness, below are additional examples to illustrate how the matching works.
+For a given request the list of `X-Forwarded-For` IPs is checked from most recent to most distant against the `excludedIPs` pool,
+and the first IP that is _not_ in the pool (if any) is returned.
+
+!!! example "Matching for clientIP"
+
+    |  X-Forwarded-For               |  excludedIPs          | clientIP     |
+    |--------------------------------|-----------------------|--------------|

+Using the previous example, the backend should return `/products/shoes/image.png` (and not `/images.png`, which Traefik would likely not be able to associate with the same backend).
 
 ### `forceSlash`
 
 _Optional, Default=true_
 
+The `forceSlash` option ensures the resulting stripped path is not the empty string, by replacing it with `/` when necessary.
+
+This option was added to keep the initial (non-intuitive) behavior of this middleware, in order to avoid introducing a breaking change.

+It is recommended to explicitly set `forceSlash` to `false`.

 In `v2.3`, the support of `IngressClass`, which is available since Kubernetes version `1.18`, has been introduced.
 In order to be able to use this new resource the [Kubernetes RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) must be updated. 
+
+## v2.3 to v2.4
+
+### ServersTransport
+
+In `v2.4.0`, the support of `ServersTransport` has been introduced.
+It is therefore necessary to update [RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) and [CRD](../reference/dynamic-configuration/kubernetes-crd.md) definitions.
+
+## v2.4.7 to v2.4.8
+
+### Non-ASCII Domain Names
+
+In `v2.4.8`, we introduced a new check on domain names used in HTTP router rule `Host` and `HostRegexp` expressions,
+and in TCP router rule `HostSNI` expression.
+This check ensures that provided domain names don't contain non-ASCII characters. 
+If not, an error is raised, and the associated router will be shown as invalid in the dashboard.
+
+This new behavior is intended to show what was failing silently previously and to help troubleshooting configuration issues.
+It doesn't change the support for non-ASCII domain names in routers rules, which is not part of the Traefik feature set so far.
+
+In order to use non-ASCII domain names in a router's rule, one should use the Punycode form of the domain name.
+For more information, please read the [HTTP routers rule](../routing/routers/index.md#rule) part or [TCP router rules](../routing/routers/index.md#rule_1) part of the documentation.
+
+## v2.4.8 to v2.4.9
+
+### Tracing Span
+
+In `v2.4.9`, we changed span error to log only server errors (>= 500).
+
+## v2.4.9 to v2.4.10
+
+### K8S CrossNamespace
+
+In `v2.4.10`, the default value for `allowCrossNamespace` has been changed to `false`.
+
+### K8S ExternalName Service
+
+In `v2.4.10`, by default, it is no longer authorized to reference Kubernetes ExternalName services.
+To allow it, the `allowExternalNameServices` option should be set to `true`.
+
+## v2.4 to v2.5
+
+### Kubernetes CRD
+
+In `v2.5`, the [Traefik CRDs](../reference/dynamic-configuration/kubernetes-crd.md#definitions) have been updated to support the new API version `apiextensions.k8s.io/v1`. 
+As required by `apiextensions.k8s.io/v1`, we have included the OpenAPI validation schema. 
+
+After deploying the new [Traefik CRDs](../reference/dynamic-configuration/kubernetes-crd.md#definitions), the resources will be validated only on creation or update.
+
+Please note that the unknown fields will not be pruned when migrating from `apiextensions.k8s.io/v1beta1` to `apiextensions.k8s.io/v1` CRDs.
+For more details check out the official [documentation](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#specifying-a-structural-schema).
+
+### Kubernetes Ingress
+
+Traefik v2.5 moves forward for the Ingress provider to support Kubernetes v1.22.
+
+Traefik now supports only v1.14+ Kubernetes clusters, which means the support of `extensions/v1beta1` API Version ingresses has been dropped.
+
+The `extensions/v1beta1` API Version should now be replaced either by `networking.k8s.io/v1beta1` or by `networking.k8s.io/v1` (as of Kubernetes v1.19+).
+
+The support of the `networking.k8s.io/v1beta1` API Version will stop in Kubernetes v1.22.
+
+### Headers middleware: ssl redirect options
+
+`sslRedirect`, `sslTemporaryRedirect`, `sslHost` and `sslForceHost` are deprecated in Traefik v2.5.
+
+For simple HTTP to HTTPS redirection, you may use [EntryPoints redirections](../routing/entrypoints.md#redirection).
+
+For more advanced use cases, you can use either the [RedirectScheme middleware](../middlewares/http/redirectscheme.md) or the [RedirectRegex middleware](../middlewares/http/redirectregex.md).
+
+### Headers middleware: accessControlAllowOrigin
+
+`accessControlAllowOrigin` is no longer supported in Traefik v2.5.
+
+### X.509 CommonName Deprecation Bis
+
+Following up on the deprecation started [previously](#x509-commonname-deprecation),
+as the `x509ignoreCN=0` value for the `GODEBUG` is [deprecated in Go 1.17](https://tip.golang.org/doc/go1.17#crypto/x509),
+the legacy behavior related to the CommonName field can not be enabled at all anymore.
