think about a process page. it process all information coming from other pages and goes back to the page referer..
page1.php
<A href="process.php?param1=$foo"> Process One </a>
page2.php
<A href="process.php?param1=$zoo"> Process Two </a>
now the process.php will do something and come up with some changes on db and will go back where it came from...
Everything is fine but I cannot make process page redirec to the referer page. Any suggestions?
