Forum OpenACS Q&A: Re: How to force login for the Site?
But that isn't what Nima is asking for. From what he's said so far, sounds like all he needs is to restrict access to a bunch PHP pages to users who pass certain OpenACS-based authentication checks (must be logged in, must be a member of the university, etc.) As long as he can predict the URLs of those PHP pages and code them into a registered filter, he's set. He doesn't actually need any communication at all between PHP and Tcl, he just needs AOLserver to refuse to serve the PHP pages unless you're logged into OpenACS, and to redirect to the OpenACS login page if you're not. Should be easy.
