Hi, im new here so please be nice
Im wondering if there is a way to make a HTML page which can only be hit once. Basically, I want to see if its viable to run a competition to win tickets to a show, where by the user would have to find an object on the website, which can then be clicked on, taking them to claim their tickets. However, for obvious reasons I only want this link to work once and then maybe re-direct everyone else to a "try again soon" page. I have a few ideas, but stuck on the execution.
An idea I had was a hit counter with a PHP if condition. Basically if the hit counter is at 1. then redirect to the try again page.
Any idea, or am I clutching at straws.
Thanks in advance,
