It won't redirect when you reload which page?

Do you redirect when the form processing is done, or just when you don't have enough input? Keep in mind that reloading a submission generally resubmits the data (unless you redirect after processing it). That's why browsers issue warnings about resubmitting a POST request.

Also:

You'll need to redirect to 'http://www.mysite.com' instead of 'www.mysite.com';

Should you be using a POST method or a GET method in your form submission?

Please don't mix the object oriented CGI interface with the functional one, it hurts my eyes.
