Alternatives to CGI

I've heard many web host don't allow cgi due to security reasons. i was wondering what those reasons were and what are the alternatives to processing a form input. Is Asp one of them. Can it be used to process forms and can javascript?

Thanks much.

ASP can be used to process forms, PHP and Java to name but a few. Of course, all of these languages have other uses too :-)
JavaScript is a client-side technology so the functionality in this aspect is limited. It reallys heavily on the users PC and to that end is a bit unreliable.
For example if your form was to send an e-mail to someone, with JS and HTML you would rely on the users e-mail client and security settings to enable the mail to be sent. The mail would be sent from the clients default e-mail address, which some people are against (fear of spam etc..)

Thank you jabba for you responses. Do you know if C can be used to process forms. My idea is to have a form on a LAN that 5 to 10 ppl could use at any time fill out periodically and then submit it. The forms would then be processed by the server on the lan - or the main computer - however will i not need a client/server architecteture to accomplish this so many ppl can access it simultaneoulsy? Thank you agian.

C could be used, but you could signficantly reduce your development time by using PHP or Perl to do this.
