     sslconfigprovclient.hxx

   Abstract:
     SSL CONFIG PROV client

     Client provides easy way of retrieving SSL related parameters
     through named pipes.
     Only one pipe connection is currently supported and 
     all client threads have to share it 
     ( exclusive access is maintained by locking )

     
     Client side is guaranteed not to use any COM stuff.
     Not using COM was requirement from NT Security folks
     to enable HTTPFilter be hosted in lsass
