Perl Question?

[Jeffrey Utter]

I have a perl script running on my server that takes in part of a url as
it's argument then loads the appropriate page.

Here is an example:   say I want to load  /user/Jeff/page/

well the call to the script looks like script.pl?/user/Jeff/page/
This is kind of like a big wrapper to go around any other html code I
happen to create so I don't have to type it over and over again.  

anyway the question is:  Is there a way I can have a perl script tell the
webserver that it had a 404 error?  so the server 404 page is generated as
a response.  

Apache 1.3.9 on FreeBSD 4.3

Thanks,
