I just notice that everytime I use a stack/opaque question, the webserver gets another copy of the wsdl file--looks somewhat inefficient, especially since I have soap caching on in my php.ini file.
Nay suggestions what I am doing wrong?
Hmm. At one point when developing Opaque I had to fight really hard to stop it caching the WSDL! I don't think I left any debug code in there. It would certainly be good if you had any time to investigate this. It needs to be fixed.
