asp.net processing F5 Refresh page Repeat Submit page a thought _ practical skills

When you finish submitting a page, if we click F5 to refresh the page again, a prompt will pop up, and if we continue, we will resend the submission of the content we just submitted, if similar payment or one-time operation, we should not do so, otherwise it will cause duplicate submissions. To solve this problem, we can deal with the following ideas:

1. After the commit is successful, save a successful status in session and reload the page.

2. In the Page_Load method, determine the status value of the Session field and, if successful, display the success message, or the error prompt, followed by the Session.remove () method to empty the cache.
