I might be doing this wrong, but this is what I do.
I have a domain, apexoffers and i have a subdirectory called "offers" on that domain.
I use the following syntax and create a page called WHATEVERIWANTTOCALLTHEPAGE.php, and FTP it into the "offers" folder.
CONTENTS OF THIS PAGE:
<?php
header('Location: affiliatelinkhere?);
?>
My link to put in my ad is:
http://www.yourdomain.com/DIRECTORYNAME/DESTINATION(CLOAKED)NAME.php
SO:
If I had a football offer from footballoffers.com/offer1.html for instance I would do this:
I would create the page and replace affiliatelinkhere with the path
www.footballoffers.com/offer1.html
I would name this page football.php and FTP it to the "offers" folder.
Then I would use the link
www.apexoffers.com/offers/football.php as the link in my ad.
When someone clicks on the
www.apexoffers.com/offers/football.php link they are immediately redirected to
www.footballoffers.com/football1.html
If I want to track everything or strip out the referrer, I put the affiliate link into Prosper202, then use the tracking link Prosper gives me to replace affiliatelinkhere on the redirect page instead of the original affiliate link.
You can reduce the length of the URL by having a short domain name and not using a sub-directory. This also keeps all data in house.
