[development] avoid resubmitting a form when refreshing

[Randy Fay]

I suspect you didn't use Drupall's Form API - and you should. If you're not
using it, then you can use the Form Examples in the Examples project to come
up to speed on it - http://drupal.org/project/examples. The default behavior
of the Form API is to not do what you're concerned about.

In Drupal, one would not normally use $_REQUEST, $_GET, and friends (or only
as a last resort). Normally you use more Drupal-esqe APIs.
