2025-03-19net/http/httputil: don't call WriteHeader after HijackDamien Neil
CL 637939 changed ReverseProxy to report errors encountered when copying data on an hijacked connection. This is generally not useful, and when using the default error handler results in WriteHeader being called on a hijacked connection. While this is harmless with standard net/http ResponseWriter implementations, it can confuse middleware layers.

2022-12-21net/http/httputil: don't add X-Forwarded-{Host,Proto} after invoking ↵Damien Neil
Director funcs This reverts CL 407414. When forwarding an inbound request that contains an existing X-Forwarded-Host or X-Forwarded-Proto header, a proxy might want to preserve the header from the inbound request, replace it with its own header, or not include any header at all. CL 407414 replaces inbound X-Forwarded-{Host,Proto} headers by default, and allows a Director func to disable sending these headers at all. However, the Director hook API isn't sufficiently flexible to permit the previous behavior of preserving inbound values unchanged. The new Rewrite API does have this flexibility; users of Rewrite can easily pick the exact behavior they want. Revert the change to ReverseProxy when using a Director func. Users who want a convenient way to set X-Forwarded-* headers to reasonable values can migrate to Rewrite at their convenience, and users depending on the current behavior will be unaffected. For #50465. Fixes #57132.

2022-08-16net/http/httputil: add ReverseProxy.RewriteDamien Neil
Add a new Rewrite hook to ReverseProxy, superseding the Director hook. Director does not distinguish between the inbound and outbound request, which makes it possible for headers added by Director to be inadvertently removed before forwarding if they are listed in the inbound request's Connection header. Rewrite accepts a value containing the inbound and outbound requests, with hop-by-hop headers already removed from the outbound request, avoiding this problem. ReverseProxy's appends the client IP to the inbound X-Forwarded-For header by default. Users must manually delete untrusted X-Forwarded-For values. When used with a Rewrite hook, ReverseProxy now strips X-Forwarded-* headers by default. NewSingleHostReverseProxy creates a proxy that does not rewrite the Host header of inbound requests. Changing this behavior is cumbersome, as it requires wrapping the Director function created by NewSingleHostReverseProxy. The Rewrite hook's ProxyRequest parameter provides a SetURL method that provides equivalent functionality to NewSingleHostReverseProxy, rewrites the Host header by default, and can be more easily extended with additional customizations. Fixes #28168. Fixes #50580. Fixes #53002.

2021-10-13net/http/httputil: allow MIME parameters when detecting SSE in ReverseProxyJames Harris
This change allows httputil.ReverseProxy to detect SSE (server-sent events) content when the response's Content-Type header includes MIME parameters, such as "text/event-stream;charset=utf-8". Prior to this change the value of the Content-Type header was compared directly to the literal "text/event-stream". This caused a false-negative which failed to set the FlushInterval correctly when MIME parameters were present.

2021-07-30net/http/httputil: close incoming ReverseProxy request bodyDamien Neil
Reading from an incoming request body after the request handler aborts with a panic can cause a panic, becuse http.Server does not (contrary to its documentation) close the request body in this case. Always close the incoming request body in ReverseProxy.ServeHTTP to ensure that any in-flight outgoing requests using the body do not read from it.

2020-05-02net/http/httputil: handle escaped paths in SingleHostReverseProxyDaniel Kumor
When forwarding a request, a SingleHostReverseProxy appends the request's path to the target URL's path. However, if certain path elements are encoded, (such as %2F for slash in either the request or target path), simply joining the URL.Path elements is not sufficient, since the field holds the decoded path. Since 87a605, the RawPath field was added which holds a decoding hint for the URL. When joining URL paths, this decoding hint needs to be taken into consideration. As an example, if the target URL.Path is /a/b, and URL.RawPath is /a%2Fb, joining the path with /c should result in /a/b/c in URL.Path, and /a%2Fb/c in RawPath. The added joinURLPath function combines the two URL's Paths, while taking into account escaping, and replaces the previously used singleJoiningSlash in NewSingleHostReverseProxy.
