Subject [PATCH] new proxy hook 2.1
Date Fri, 01 Jul 2005 14:55:41 GMT
This patch adds a new hook (request_status) that gets ran in proxy_handler
just before the final return.  This gives modules an opportunity to do
something based on the proxy status.

A couple of examples where this is useful:

-You are using a caching module and would rather return stale content rather
than an error to the client if the origin is down.

-you proxy some subrequests (using SSI - mod_include) and do not want SSI
errors when the backend is down. If you would normally return
HTTP_BAD_GATEWAY, you may have a module that serves some other content.

This feature is one of the features of our in house proxy module that keeps
us from moving toward the "stock" 2.1 proxy.
