We use ISA only as a caching server (in a w2k environment) and are having problems running webex demos. It appears we have 2 options for getting round this. One is to have our users add in the webex site as an exception on the client desktops under Internet Explorer properties, Conections, LAN Settings, Proxy Server, Advanced. The second option would be to add this site as an exception on the ISA caching server. However, i don't know where to do this. I have looked all over but do not see where to do this.
