I am not 100 % sure if this is a PHP or HTML question. But I am posting it here.

I am still working on my searching engine. And I have it working, but I want to modify it a bit. When you are searching this forum, you will first have a page up saying something like searching. And after it is finished then it is showing the results. How can I do that??? How can I redirect the page from the "Searching" page to the page with the results, and at the same time sending the results in variables????
