Describe the feature request

Please add prefix stripping to frp http proxy type (similar to static_file)

I typically use frp http proxy similar to

serverAddr = "frp.example.com"
serverPort = 7000

[[proxies]]
name = "fast"
type = "http"
localIP = "127.0.0.1"
localPort = 5000
customDomains = ["frp.example.com"]
locations = ["/r/fast"]

then I navigate to
frp.example.com/r/fast to get to my proxied page. However, this requirers my target application to be aware that the incoming http path is /r/fast, which can be inconvenient.

I've added the ability to "strip prefix" for any locations defined. This is useful if the target can't be aware of paths and expects paths at /

obviously there are tonsof other ways get around this outside of frp, but usually involves adding another reverse proxy in the chain. I find it convenient for my usecase to have the prefix stripping ability built into frp.

I'm using this config instead:

name = "fast"
type = "http"
localIP = "127.0.0.1"
localPort = 5000
customDomains = ["frp.example.com"]
locations = ["/r/fast"]
stripPrefix = true

this specifically will strip any locations defined in locations

The strip logic is implemented in http.go in the same block that we rewrite the host when requested.

Right now, frp isn’t a fully featured L7 proxy.

We don’t plan to add such features one by one for the time being. You can prioritize using it together with other proxies.

Very well, I will fork this project, implementing this functionality, and until such time it makes sense to add similar prefix stripping like in the static file plugin, I will open a PR.

@cayspekko I saw your fork and tried it using your built Docker Container. It worked flawlessly.
Do you still intend to open a Pull Request?
