You may be right, and I found the same references to ISAPI (specifically, how to handle HSE_STATUS_PENDING in ASP).

However, the SSI #exec makes a distinction between executing via CGI and EXE, so I assume that it will handle CGI.

It may well be that it is not possible to #exec a perl cgi program under IIS. I have only been playing around with this and I haven't had a lot of time to investigate it in detail (I was just hoping somebody here might have come across it before).

I'm going to play around a bit more and see if I can come up with something.

If I find a solution, I'll post something here ;-)

Jim.
