CGI Location #1597
Description
Should http/cgi default to a 3xx status if the child returns a "Location" header but no explicit status? http://www.ietf.org/rfc/rfc3875 Also, might want to support server-fetched redirects if the caller opts-in by defining a FetchingRedirectClient *http.Client in their handler struct: 6.3.2. Location The Location header field is used to specify to the server that the script is returning a reference to a document rather than an actual document (see sections 6.2.3 and 6.2.4). It is either an absolute URI (optionally with a fragment identifier), indicating that the client is to fetch the referenced document, or a local URI path (optionally with a query string), indicating that the server is to fetch the referenced document and return it to the client as the response. Location = local-Location | client-Location client-Location = "Location:" fragment-URI NL local-Location = "Location:" local-pathquery NL fragment-URI = absoluteURI [ "#" fragment ] fragment = *uric local-pathquery = abs-path [ "?" query-string ] abs-path = "/" path-segments path-segments = segment *( "/" segment ) segment = *pchar pchar = unreserved | escaped | extra extra = ":" | "@" | "&" | "=" | "+" | "$" | "," The syntax of an absoluteURI is incorporated into this document from that specified in RFC 2396 [2] and RFC 2732 [7]. A valid absoluteURI always starts with the name of scheme followed by ":"; scheme names start with a letter and continue with alphanumerics, "+", "-" or ".". The local URI path and query must be an absolute path, and not a relative path or NULL, and hence must start with a "/". Note that any message-body attached to the request (such as for a POST request) may not be available to the resource that is the target of the redirect.
