When you hit the refresh button, the web browser re-sends the last request made to the server in order to "refresh" the page.

When your last request caused information to be submitted to the server (through clicking a button, selecting a value in a drop down list that causes a post back to the server, etc etc) the web browser warns you that you are about to submit the same data again.

This is very important to know.
Say you have a shopping cart and check out...you click a button and the sale is processed and a charge is made to your credit card. Now you hit the refresh button. The last request is sent to the server again, which means you are requesting the server process the sale again, and means that your credit card is going to be charged twice for the same product.

So it's not a problem that your web browser is issuing this warning when you hit the refresh button.
