    I have a very simple asp.net web page that when a user clicks submit, it stores data to a sql database and sends an email notification.   It works fine, unless when you close Edge, and have "Previous Pages" selected as the setting for "Open Microsoft Edge With".  In that case, the next time a user opens Edge, all the pages re-open and the form re-submits.  

    Looking to see how to prevent this?  What would you suggest?

    This situation is commonly solved using the POST/GET/Redirect pattern.
