Hello Andre,
We are proxying request from apache to tomcat using mod_proxy and mod_proxy_ajp
Following is the load balancer configuration in apache.
kindly let me know in case you need further details.

Ok, sorry, I confused your post with another one.
But anyway, your configuration shows a whole lot of proxy modules, many of
which do not seem to have any relation with proxying calls to Tomcat. Such as
these :
>> LoadModule proxy_connect_module modules/mod_proxy_connect.so
>> LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
>> LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
The following /may/ have a relation with the proxying to Tomcat, but which one
are you really using ?
>> LoadModule proxy_http_module modules/mod_proxy_http.so
>> LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
Usually, people use *either* mod_proxy_http *or* mod_proxy_ajp, so which one is
being used ? Can you provide some information about the apache httpd
configuration that shows what is being proxied and how ?

I thought that Pid already pointed that out.
