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 =20 =20 =20 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 =20 =09 ------------------------------------------------------------------------ -------- Apache/2.2.3 (Fedora) Server at testingserver.test.com Port 443 =20 =20 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.=20 --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
