Hi all, I am trying to configure the latest Apache 2.2.x on Windows 7 64bit (so using 32bit emulation) as a Reverse Proxy with Load Balancing. I can get the reverse proxy side of things to work. The load balancing too works if the origin servers work. But if I configure it to go to a port that is not listened to, then I get a 502 every second request and the balancer worker is never put into error state. Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request /GET <http://localhost:8081/qlikview/index.htm>/--deleted--/ Reason: *Error reading from remote server* Now I've pulled my hair out looking through Google, so I downloaded the code and started to reverse engineer how Apache works. My C is pretty rusty but I'm getting there. The code looks like it tries to read the status line off the response from a dummy request object, fails to do that and sends a 502 without placing the worker into error. In fact I can't see anywhere where we can place a worker into error due to a connection problem. The only place I see is if the status code matches a list of status codes that come from the configuration in an undocumented config option that doesn't seem to work for me. Any ideas?
Please provide your full Apache version and the relevant parts of your proxy configuration.
