They must have changed their protocol. What are the contents sent to this URL? If it looks like an authentication request, you could try to copy the line with the handler for /auth as a handler for /VPN in worker-http.c. I.e., add: LL("/VPN", get_auth_handler, post_auth_handler), in the known_urls table. regards, Nikos
