This approach won't help users of the Wine conformance tests running
on Windows, so it appears to me to be a flawed approach. We should
instead rewrite any existing tests that use a public server to instead
use a server started by the Wine test code (see
dlls/wininet/tests/http.c:server_thread). This has the additional
benefit of allowing us to be much more precise with what we're testing
and to be able to emulate the implementations of different HTTP
servers, instead of just what winehq.org runs.
