[Fedora-suds-list] Clearing Cached Schema

I've just started evaluating SUPS to implement a simple WSDL client, but I've run into a dead end when I changed a method name in my schema. Apparently, even though I'm disabling the cache with client.set_options(cache=None), it's still managed to cache the old schema. How can I truly disable all caching, and clear any currently cached wsdl schema? Where does SUPS store cached data on Windows? Regards, Chris
