Getting virtual() to work

The cgi script now works, but php's virtual doesn't

[donovanh]

Hi,

I'm running PHP as a module, and trying to understand why the virtual command isn't working.. it's phrased like this:

virtual("/cgi-bin/home.cgi");

Testing the script in the browser works, and it does return a content-type header. However when running this virtual command, I get no error message, just a blank screen.

What could be causing this?
