NATS3 Link Codes
Affiliate Link Code page. There are two types of link codes: encoded and unencoded. The difference is depicted in Figures 1.1, 1.1a, and 1.1b:
As you can see, encoded linkcodes provide the most affiliate protection: the affiliate, campaign, program, and site information cannot be altered in the query string.
Redirecting to the Correct Page
When NATS turns a linkcode into a tour URL, it automatically appends a slash (/) to the end of barewords. You can prevent this by appending a question mark to the end of the URL. For example:
|Tour URL||Where Linkcodes Go|
Qualified Link Codes
If there's a extra "t" in your linkcode, you probably grabbed the wrong link code from the top of the Sites edit page.
http://join.site.com/ttrack/<?=(!empty($_REQUEST['nats']) && !preg_match('/[\'\"<>()\\\+\[\]]/', $_REQUEST['nats']))?$_REQUEST['nats']:'MDowOjE'?>/page.html
The ttrack is used for qualified clicks; track is used for normal hits.
