Anybody have an idea what will be causing the issue? After few refresh on the page I will get actual page but most of the times end up with below proxy error Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /testingtool/. Reason: Error reading from remote server ------------------------------------------------------------------------ -------- Apache/2.2.3 (Fedora) Server at testingserver.test.com Port 443 Thanks, Isha Aoache is the proxy, is it? It could be the back-end server is not working reliably - what happens if you access it drectly? If it seems OK, how long does it take to respond? If it's a slow application it may take longer than apache is prepared to wait (see ProxyTimeout, KeepAlivetimeout) Rgds, Owen Boyle Disclaimer: Any disclaimer attached to this message may be ignored. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
