We use Akamai for the redirection. We have to track the original URL before we do the redirection. We are checking with Akamai how to pull the original URL. We can pull the URL from backend c#. How can we set that variable as s.referrer. Any thoughts?
As you are using Akamai for redirection , I assume you are doing server side redirection i.e. the web server has been configured to point the user to another URL. Please see the following links for information on implementing analytics for URL Redirects.
