Pear SOAP - using WSDL but different endpoint and sending cookies

A quick question about the latest version of Pear SOAP... I want to use WSDL, but I want to a) specify a different endpoint than is in the WSDL b) send a cookie c) use WSDL caching So, if I use SOAP_Client, I don't see a direct way to change the endpoint ($_endpoint is ignored in favor of the WSDL 'location'). And I don't see how to engage WSDL caching. $myclient = new SOAP_Client(WSDL_PATH, true, false); $myclient->_wsdl->services['myname']['ports']['myname']['address']['location'] = $newloc; $myclient->setOpt('cookies', $cookies ); If I use SOAP_WSDL, I can engage WSDL caching, but I still have the endpoint issue, and I cannot see any way to send a cookie: $wsdl = new SOAP_WSDL(WSDL_PATH, null, true); $wsdl->services['myname']['ports']['myname']['address']['location'] = $newloc; $myclient = $wsdl->getProxy(); Do I have to extend this proxy class with methods to do all this stuff?
