Here is an html example using the meta refresh tag...
<HTML>
<HEAD>
<META HTTP-EQUIV="refresh" content="2;URL=http://www.yoursite.com/results.php">
<TITLE>Please wait...</TITLE>
</HEAD>
<BODY>
SEARCHING, PLEASE WAIT...
</BODY>
</HTML>
You can change the content="2; with any number, that is how long it waits on the current page
Hope this helps.
