# Integration with proxies
|
|
|
|
**Authelia** works in collaboration with reverse proxies. In the sub-pages you
|
|
can find the documentation of the configuration required for every supported
|
|
proxy.
|
|
|
|
If you are not aware of the workflow of an authentication request, reading this
|
|
[documentation](../../home/architecture.md) first is highly recommended.
|
|
|
|
|
|
## How Authelia integrates with proxies?
|
|
|
|
Authelia takes authentication requests coming from the proxy and targeting the
|
|
`/api/verify` endpoint exposed by Authelia. Two pieces of information are required for
|
|
Authelia to be able to authenticate the user request:
|
|
|
|
* The session cookie or a `Proxy-Authorization` header (see [single factor authentication](../../features/single-factor.md)).
|
|
* The target URL of the user request (used primarily for [access control](../../features/access-control.md)).
|
|
|
|
The target URL can be provided using one of the following ways:
|
|
|
|
* With `X-Original-URL` header containing the complete URL of the initial request.
|
|
* With a combination of `X-Forwarded-Proto`, `X-Forwarded-Host` and `X-Forwarded-URI` headers.
|
|
|
|
In the case of Traefik, these headers are automatically provided and therefore don't
|
|
appear in the configuration examples.
|
|
|
|
## Redirection to the login portal
|
|
|
|
The endpoint `/api/verify` has different behaviors depending on whether
|
|
the `rd` (for redirection) query parameter is provided.
|
|
|
|
If redirection parameter is provided and contains the URL to the login portal
|
|
served by Authelia, the request will either generate a 200 response
|
|
if the request is authenticated or perform a redirection (302 response) to the
|
|
login portal if not authenticated yet.
|
|
|
|
If no redirection parameter is provided, the response code is either 200 or 401. The
|
|
redirection must then be handled by the proxy when an error is detected
|
|
(see [nginx](./nginx.md) example).
