There is a form ,which is submitted and then the page is redirected to another page.But if the user hits the refresh button again on the new page .the following message is displayed

To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

And on press "OK"

A duplicate entry is created how do i prevent this or how do i handle this

I am using a django,application
