Re-load behavior not in PHP?

Anon

In PHP, if you load information from a form into a php file, it accepts the input, acts on it, and produces a page. If you use the "re-load" button while on this second page, the action is repeated as though the form from the previous page was submitted again.

Is this behavior consistent with other languages? If Perl were the scripting language of choice, and all other factors were the same, would it behave any differently?

Thanks,

Ben

When you click on the refresh, or re-load button the browser actually behaves as if it did go back to the previous page and "press the submit button". The server sees the form submitted again, with the same referrer. Tough to get around this unless you log the entry and check for it.

If you have the form send the information to a page that just processes the information then redirects the user to a 'success' page then you won't have that problem.

nice!

i'd relied before on the users not being muppets (this is reasonable because most of the data input screens are only used in-house, and i can shout at people if they're stupid ;-) ), but that's a clever peice of defensive coding.
