// If a response to a non-safe HTTP request-method contains the Location- or
|
|
// Content-Location header, we must make sure to invalidate any cached entry
|
|
// representing the URIs pointed to by either header. RFC 2616 section 13.10
|
|
//
|
|
// This test uses 3 URIs: "/post" is the target of a POST-request and always
|
|
// redirects (301) to "/redirect". The URIs "/redirect" and "/cl" both counts
|
|
// the number of loads from the server (handler). The response from "/post"
|
|
// always contains the headers "Location: /redirect" and "Content-Location:
|
|
// /cl", whose cached entries are to be invalidated. The tests verifies that
|
|
// "/redirect" and "/cl" are loaded from server the expected number of times.
