Adding referrer check to existing script

This is my first post here folks so be gentle with me. I am not a PERL guy at all, but I am using a suite a perl scripts (ez scripts if anyone has heard of them) for a simple project I am doing. I have recently hit a streak of spam coming from outside my domain (obviously) Until I can convert my whole system over to php I wanted to at least add a referrer check the the head of the script if possible. This will at least slow down my spamming issue. Is it even possible to add a simple referrer check to the script and if so what would the code look like? Thanks to any help out there!

welcome to WebmasterWorld [webmasterworld.com], newjay1000!

have you tried checking the ENV hash?

if there is a referrer and it has been set by the user agent and is passed through to the web server then $ENV{HTTP_REFERER} will have that value in your script.

be aware that there are often cases where the request is referred but the referrer is not specified in the request.
