## Configuration Options
|
|
|
|
### General
|
|
|
|
The StripPrefix middleware will:
|
|
|
|
- strip the matching path prefix.
|
|
- store the matching path prefix in a `X-Forwarded-Prefix` header.
|
|
|
|
!!! tip
|
|
|
|
Use a `StripPrefix` middleware if your backend listens on the root path (`/`) but should be routeable on a specific prefix.
|
|
|
|
### `prefixes`
|
|
|
|
The `prefixes` option defines the prefixes to strip from the request URL.
|
|
|
|
For instance, `/products` would match `/products` but also `/products/shoes` and `/products/shirts`.
|
|
|
|
Since the path is stripped prior to forwarding, your backend is expected to listen on `/`.
|
|
|
|
If your backend is serving assets (e.g., images or Javascript files), chances are it must return properly constructed relative URLs.
|
|
Continuing on the 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).
|
|
|
|
The `X-Forwarded-Prefix` header can be queried to build such URLs dynamically.
