By default, if a user clicks on the affiliate link, they are redirected to the home page.
You can change the default from home page to another page in dap setup -> config section.

But if you want to redirect users to a different page, then use the p tag as described below:

Affiliate Link To Specific Page:

To link to a specific page, just add the text "&p=<insert_url_here>" to the end of your affiliate link, like this: (no "http://" in the 2nd link at the end - should start with "www")

For ex:
http://YOURSITE.com/dap/a/?a=101&p=w.../somepage.html

Now when a prospect clicks on the affiliate link (http://YOURSITE.com/dap/a/?a=101), they will be redirected to www.example.com/somepage.html
