Path-based routing is not working for me. As an example, I set prefix to /jellyfin, website is reachable at https://jellyfin.homelab.com/ pointing to resource 192.168.0.5:8096 but when I visit https://jellyfin.homelab.com/jellyfin nothing comes up.

It looks like Pangolin's Blueprints feature is missing the "stripprefix" feature that Traefik has. I often want to route a subpath (path prefix) without the underlying service being aware of it. E.g:

labels:
  - traefik.enable=true
  - traefik.docker.network=traefik
  - traefik.http.routers.example-api.rule=(Host(`example.com`) && PathPrefix(`/api`))
  - traefik.http.middlewares.stripprefix-api.stripprefix.prefixes=/api
  - traefik.http.routers.example-api.middlewares=stripprefix-api

Without Pangolin actually stripping the prefix, this feature is a bit neutered. Was this an oversight? Since Pangolin is all Traefik in the background it shouldn't be too hard to implement, hopefully?

Yeah we should add this. Pretty trivial. Will look into soon.

Thanks for implementing this in v1.11.0! It works great!

The strip prefix option works great when configured through the UI for me, but when configuring it through Docker labels it seems that you MUST set a rewritePath for it to work. The UI sets the value to an empty string, but that doesn't seem possible when using the labels, so therefore it breaks. Thankfully, setting rewritePath=/ seems to be equivalent.

Also these labels don't seem documented yet: https://docs.pangolin.net/manage/blueprints#target-configuration

This is how I configure my target in Docker labels:

- pangolin.proxy-resources.paperless.targets[0].method=http
- pangolin.proxy-resources.paperless.targets[0].path=/paperless
- pangolin.proxy-resources.paperless.targets[0].path-match=prefix
- pangolin.proxy-resources.paperless.targets[0].rewrite-match=stripPrefix
- pangolin.proxy-resources.paperless.targets[0].rewritePath=/ # <-- If this is left out, it breaks!

@sippeangelo thanks for pointing this out! I have updated the docs and in c16e762fa4 I have made it so that the rewritePath is now rewrite-path and is backwards compatible with this old version. I have also made it so that the / is included by default.
