You cannot stop user from hitting the refresh button of his browser. whenever he does that the browser will request the server for the page.<BR><BR>Now it upto the server to decide if it is(the page) requested again or for the first time. So it is you who will have to take care of the web page requests.
That i know that we cant stop users from hitting refresh button, i have one way to stop executing the page even after user hits the refresh button, that way is session but it's not an handsome way. I want any other methos than this
then set up a hidden field value when you display the page.<BR>afterwards when it is requested again, check the value in the hidden field. if it is what you sent earlier on the page, do not process the page further.<BR>
