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.

2022-09-23net/http/httputil: avoid query parameter smugglingDamien Neil
Query parameter smuggling occurs when a proxy's interpretation of query parameters differs from that of a downstream server. Change ReverseProxy to avoid forwarding ignored query parameters. Remove unparsable query parameters from the outbound request * if req.Form != nil after calling ReverseProxy.Director; and * before calling ReverseProxy.Rewrite.

Support for 1xx responses has recently been merged in net/http (CL 269997). As discussed in this CL (https://go-review.googlesource.com/c/go/+/269997/comments/1ff70bef_c25a829a), support for forwarding 1xx responses in ReverseProxy has been extracted in this separate patch. According to RFC 7231, "a proxy MUST forward 1xx responses unless the proxy itself requested the generation of the 1xx response". Consequently, all received 1xx responses are automatically forwarded as long as the underlying transport supports ClientTrace.Got1xxResponse.

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.

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.

2020-01-21net/http/httputil: add docs about X-Forwarded-For in ReverseProxyKévin Dunglas
ReverseProxy automatically sets the X-Forwarded-For header, if the request already contains a X-Forwarded-For header, the value of the client IP is appended to the existing header value. This behavior isn't documented anywhere, and can lead to IP spoofing security issues is the client is untrusted (the most common situation). This PR documents this behavior. For future versions, I proposed #36678 that implements a more secure default behavior and adds support for other forwarded headers.

2019-11-02net/http/httputil: fix missing Transfer-Encoding headerHarshavardhana
Current implementation of httputil.DumpRequestOut incorrectly resets the Request.Body prematurely before Content-Length/Transfer-Encoding detection in newTransferWriter() This fix avoids resetting the Request.Body when Request.ContentLength is set to '0' by the caller and Request.Body is set to a custom reader. To allow newTransferWriter() to treat this situation as 'Transfer-Encoding: chunked'.

2019-07-17net/http/httputil: fix regression in ReverseProxy.ServeHTTPJoe Tsai
In Go1.12 and below, the logic in ReverseProxy.ServeHTTP would always allocate request.Header even if it were not present in the incoming request. CL 174324 added http.Request.Clone and re-factors ReverseProxy.ServeHTTP to use the new Clone method. However, the new Clone logic is not equivalent to the former logic. We preserve former semantics by explicitly allocating the Header map if nil.

2019-05-17net/http/httputil: remove os.Stderr claim in ReverseProxy.ErrorLog docsDmitri Shuralyov
The motivation for doing so is to avoid making inaccurate claims. Logging may not go to os.Stderr if anyone overrides the log package's default output via https://godoc.org/log#SetOutput. Saying that the standard logger is used should be sufficient to explain the behavior, and users can infer that os.Stderr is used by default, unless it's changed. This change is the same as what was applied to http.Server.ErrorLog documentation in CL 53950.

KeepAlive field used to report the wording "keep-alive period" which may be misleading.

2019-03-11all: move internal/x to vendor/golang.org/x and revendor using 'go mod vendor'Bryan C. Mills
This also updates the vendored-in versions of several packages: 'go mod vendor' selects a consistent version of each module, but we had previously vendored an ad-hoc selection of packages. Notably, x/crypto/hkdf was previously vendored in at a much newer commit than the rest of x/crypto. Bringing the rest of x/crypto up to that commit introduced an import of golang.org/x/sys/cpu, which broke the js/wasm build, requiring an upgrade of x/sys to pick up CL 165749.

2019-02-13net/http/httputil: make TestDumpRequest idempotentEmmanuel T Odeke
TestDumpRequest was failing with -count=2 or more because for test cases that involved mustReadRequest, the body was created as a *bufio.Reader. DumpRequest and DumpRequestOut would then read the body until EOF and would close it after use. However, on re-runs of the test, the body would be terminally exhausted and result in an unexpected error "http: invalid Read on closed Body". The update to the test cases adds an extra field "GetReq" which allows us to construct requests per run of the tests and hence make the test indefinitely re-runnable/idempotent. "Req" or "GetReq" are mutually exclusive: either one of them can be set or nil, but not both.
