	Subject: [users@httpd] 502 proxy error
	When I try to access an application using reverse proxy, most of
the time I will end up with below error. 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
	The proxy server could not handle the request GET /testingtool/.
	Reason: Error reading from remote server
	Apache/2.2.3 (Fedora) Server at Port 443

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)
