Error

I'm Using Apache 2.2.16 and Tomcat 7.0.16. I have 3 Tomcat instance which
executes 3 war files. To bypass the proxy I have configured httpd with 3
workers.

3 Tomcat instances are running in 8080, 8090, 8099.

Intermittently I was getting 502 Proxy Error in 8090 and 8099 for all the POST
operations. So I have set the below variables in the httpd.conf

SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1

After setting this configuration gradually the error rate got decreased but
still we are facing some issues. 

When the request comes with HTTP/1.0 its working fine but when request comes in
HTTP/1.1 I am getting 502 Proxy Error at some times.

Please help me in resolving this issue.


Thanks,
Prakash S
