ISAPI is Internet Server Application Programming Interface.

I think both are different. ISAPI authentication is used in the IIS. Basically they are programs (non cgi executables ) written to interact with the webserver requests. There are basically 2 types of ISAPI programs. Extensions and filters. ISAPI filters can modify incoming and outgoing requests. Main problem for this method is, it can stop your webserver from working once this programs got crashed.

I am not sure regarding this. I think it is done at the end of IIS. Could you tell me why you are so specific on using this method ?

My application will be used by internal users and also users from outside. So, I cant use windows authentication. And the requirement is to use ISAPI Authentication. Any idea on how to implement this?
