I have tomcat server behind the apache. I am using mod_ssl and reverse proxy to the tomcat. All are running at default ports.

The full error is as follow. ack Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /pages/doeditpage.action.

Reason: Error reading from remote server

If I clean the browser cache the error goes away and comes back after few attempts. I test the same on Chrome/Firefox/IE on Windows platform. Wondering it works perfectly on Linux based Chrome/Firefox.

I googled a lot there are few answers at stack overflow but I am not able to find my answer. Is this a server side problem? because so many browsers cant be wrong at same time on Windows.
