I have a working regex that determines the domain to which the request should be sent, but I'm having a hard time figuring out the syntax of the proxy statement. Here's what I've tried: if (User-Name !~ <REGEX>) { proxy: domain.name else { proxy: LOCAL } } FWIW, I can successfully authenticate do the "domain.name" realm by using userid@domain.name. Can anyone offer any suggestions? Thanks in advance. -- Charles Plater Lead Application Technical Analyst Internet Services +1-313-577-4620 ab3189@wayne.edu - List info/subscribe/unsubscribe?
