I'm reworking someone else's Perl code, building CGI scripts (using CGI::Pretty). He liberally used multiple <FORM> elements in a page, a practice which was previously unfamiliar to me. Sometimes these FORM elements are nested. I'm struggling to understand the existing code.

Why use multiple FORMs? OK, they may have different 'action' tags, pointing to other CGI scripts. But most of the examples I've run across don't. So why use multiple FORMs?

When there are multiple FORMs on a page, each with its own SUBMIT, do all the param's on the page get passed? or just the ones in the FORM that encloses the SUBMIT? Is the answer different for hidden params? Is the answer the same for both GET and POST? Is the answer the same when FORM elements are nested?

Are there any suggested best practices for multiple FORMs? Are there gotcha's in using multiple FORMs?

thanks
