Subject mod_proxy and interim responses
Date Wed, 03 Oct 2007 23:41:06 GMT
RFC2616 tells us a proxy MUST forward interim (1xx) responses
to an HTTP/1.1 Client, except where the proxy itself requested
the response.  Currently mod_proxy is just eating interim
responses.  There's a history of problems here (PR#16518).

I've hacked up a simple patch, based on a new
ap_send_interim_response API function.  This works, but could
raise issues of ordering if we start to support asynchronous
pipelining of requests on a connection.

Patch attached.  Comments?
