Hi, Before upgrading to Fedora 18, I had IIS in a VM serving pages via Apache and mod_proxy. All was good and lovely. Post and get requests all worked. I upgraded. Now, post requests above a certain size fail. ProxyRequests Off ProxyPreserveHost On ProxyPass / http://127.0.0.1:8891/ connectiontimeout=5 timeout=30 Keepalive=On ProxyPassReverse / http://127.0.0.1:8891/ Tried setting: SetEnv proxy-sendchunked 0 SetEnv proxy-sendcl 1 All that happens is that the proxy server replies with: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /test. Reason: Error reading from remote server and in WindowsLand, the w3wp process that tried to receive the POST request is stuck at 100% CPU and needs killing. I'm at a complete loss with this. Have any default behaviours changed in mod_proxy? It seems to me that if a complete request is bigger than a packet, it fails, but small requests work fine, possibly? Making the request direct to IIS works. And the really frustrating thing is that this all worked with the exact same setup before I upgraded to F18 and I can't find a list of what changed in mod_proxy between 2.2 and 2.4... Does anyone have any suggestions?
