Now, I may be totally out of line here, but xburrows might not be searching for ISO (International Standards Organization... or something) documents, he might be ISO (In Search Of... or something) any technical documents regarding his question.

I interpreted xburrows's sysadm's response as if he thought Perl required some kind of dedicated application server, which of course it doesn't. However, Perl is used in such application servers, for example Apache servers and, I believe, IBM WebSphere servers (a broad enough term to be accurate).
