Sorry to be a heretic here but that's something I'd recommend some PHP thing for if you don't have any experience. Much less trouble. There are several tried and tested solutions that you can just copy to your webspace and be done with it (don't ask me any names though, I'd have to duckduck as well). Trying to do this yourself without a good understanding of how the underlying modules work is likely to lead to problems like header injection vulnerabilities. Perl modules tend to have more sensible defaults than PHP so getting it wrong is not quite as easy but still ...

That said, you could of course do a good deed for provider-side Perl support and make sure some ready-made Perl solution with its associated modules works fine on your webspace. Likewise I'd have to search for the name of any such script though.
