How to Prevent Form Resubmission when page is refreshed or back button is clicked
I was searching around for days and finally found something. IF you use a HTML command it will remove any input the user put when the user goes back. Because my problem was when the user goes back after be redirected, their information was still there but if you use

Preventing form resubmission
There are 2 approaches people used to take here:
Method 1: Use AJAX + Redirect
This way you post your form in the background using JQuery or something similar to Page2, while the user still sees page1 displayed. Upon successful posting, you redirect the browser to Page2.
Method 2: Post + Redirect to self
This is a common technique on forums. Form on Page1 posts the data to Page2, Page2 processes the data and does what needs to be done, and then it does a HTTP redirect on itself. This way the last "action" the browser remembers is a simple GET on page2, so the form is not being resubmitted upon F5.
