Restate: using php to rotate ad banners

Anyone? Reply? I recently created some scripts to rotate ad banners on my site. One script is called show.php, which serves the banner. The other is called click.php, which redirects the people to the proper site for the banner they clicked on. Some people have noticed that when they click on the banner, they go to another site. Others have noticed that they just get returned back to the page that they just were at. I test it without any problems. I have been doing the redirecting using cookies. The script show.php puts the cookie on their computer. The script click.php gets the cookie and redirects them to the proper place when clicked. Should I be using cookies or sessions to do this? I think the problem is that some people have their browser set to not accept cookies which is why they get directed to other places. __________________________________________________ Do you Yahoo!?
