Subject Form data refresh?
Date Wed, 20 Feb 2008 02:51:17 GMT
If a user adds an item to his/her shopping cart using form data like this:
How can I determine if it was generated from user clicking an add-to-cart
link vs. a browser refresh?
I don't want to increment the quantity in the cart for this item if the user
refreshes the browser but I do want to increment if the user clicks the add
button again for this item.
