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 on=
e is being used ? Can you provide some information about the apache httpd c=
onfiguration that shows what is being proxied and how ?

we can point out where exactly is the problem in the code or configuration?
>=20

I thought that Pid already pointed that out.
