How to enable Client Cert Required, only for certain URL's in the webserver

Question

WE are using netegrity siteminder for authentication and their plugin is executed as AuthTrans function. If I enable clientauth in server.xml ( which is basically turning on the client cert required for entire site), everything works fine. But If I want to turn that on only for certain URL's how do I do that.
I tried turning global clientauth off in server.xml and tried using PathCehck fn"get-client-cert" in obj.conf for the URL's that need client cert, but the problem is AuthTrans is getting executed first and my netegrity plugin is throwing an error saying it cann't find the cert.
What are diffrent options to enable cert required only for certian URL's.
Thanks

What is the condition you want to match?
You can use get-client-cert in If tags in Web Server 7.0 :
For e.g. If the condition is matched, This gets a cert, requesting it if it is not already present and failing the request if it can't obtain an acceptable cert only on POST requests.
<If $url ~="*abc*>
PathCheck fn="get-client-cert" method="POST" dorequest="1" require="1"
</If>
or
<Object ppath="*abc*">
PathCheck fn="get-client-cert" dorequest="1" require="1"
<Object>
