reverse

reverse provides a mounted reverse HTTP proxy handler with:

• target resolution
• path and query merging
• hop-by-hop header stripping
• request and response mutation hooks
• neutral observation hooks

Use it for

• /proxy/...?_target=https://upstream.example
• reverse-proxy adapters in debuggers or developer tools
• product-specific reverse proxy endpoints without hard-coding those routes into the library

Main entry point

handler, err := reverse.New(reverse.Options{
  Resolver: reverse.QueryTargetResolver{
    MountPath: "/proxy",
  },
})

Important options

Option	Meaning
Resolver	Required target resolver
RoundTripper	Custom http.RoundTripper
MutateRequest	Request mutation before transport round trip
MutateResponse	Response mutation before response is copied downstream
Hooks	Shared observation hooks
ObserveTarget	Predicate to suppress observation for selected targets
PreserveHost	Keep incoming Host instead of replacing with upstream host
SampleRequestBodyBytes	Sample limit for observed request body
SampleResponseBodyBytes	Sample limit for observed response body

Built-in resolver

QueryTargetResolver resolves _target, applies an optional default target, strips selected query parameters, and merges the request path and query into the upstream URL.

That gives you mounted reverse-proxy behavior without forcing route names into the package itself.
