Re: Server-side Form Validation (Perl)

You should validate all data recieved from a web form if only for security
reasons.

The best method is to use both Javacript on the client (fast) and then
re-check on the server, the simplest way is to just return a missing
information page and ask the user to hit back and correct the problems.
