I think i have done configurations properly with isapi_redirect.dll. I am completely unaware of what is happening. Am i using wrong isapi_redirect.dll? Do i need to do any extra configuration in tomcat except <Engine name="Catalina" defaultHost="localhost" jvmRoute="worker1">

is it ajp version as I am using ajp/1.3 in tomcat(Server.xml) and in isapi_redirect.dll configuration files using ajp12.
I have configured the workers. properties, isapi_redirect.properties file.

Any help would be much appreciated.

Thanks in Advance.
Regards & thanks,
