Embperl & CGI

[allen haim <al...@netherrealm.net>]

Thanks Andrew; that's perfect.

Another question: can I call an ordinary CGI script from within an embperl
page, and send it the parameters it needs? Of course, I can 'require' it
from within [- -] tags, but then the CGI parameters won't work right.

happy random excerpt from the Weblog of J. Alfred Prufrock:

Saturday, April 10, 2004

so ended up at fresh choice, which was SO good (want more bacon bits, vivienne? LOL!) and it was pretty cool until valerie totally took forever in the bathroom and we were all waiting to go but she said she was just preparing her face to meet the faces that she'd meet and we were like, ok. ezra seemed kind of mad at that, but i told we still had time to go to express, to murder and create, time for all the works and days of hands, and time to go to sam goody afterward to get a cd for ezra's dad's birthday. so we ate some more toast and tea and then shopped for like two more hours and my feet were tired but it was cool.

If you use Apache 2, you can include a the CGI as subrequest by issueing
something like the following:

Execute ({subreq => '/cgi-bin/script.cgi?parm=1&parm2=2'}) ;
