How can I overwrite the referrer with an empty string

Hi,

When a visitor types the URL of page A in the browser a redirect occurs to the page B.
On the B page the URL is b/?ref= and document.referrer=A

I set s.referrer = s.Util.getQueryParam("ref"); however since it's an empty string the value from document.referrer shows up.

Any advice?

Thank You!

Dear Andre,

That's the expected behavior if it is a server redirection. This is because AA referrer will not be set automatically on Page A but only on Page B where the document.referrer is Page A.

For page-level redirections, if the Adobe Analytics call was triggered before the redirection, the AA referrer value will be empty and thus you will see an empty value at the landing page (Here, Page B).

    Hi Pratheep, agree that is the default expected behavior. That's why I'm using the s.referrer to overwrite the value with an empty string. Somehow the overwrite is not working and I still get the value from document.referrer.

    @andreis65119307 If u set s.referrer = s.Util.getQueryParam("ref"); for the url b/?ref= final value of s.referrer will be empty (s.referrer = ' ');, Appmeasurement library will considered this as s.referrer is not defined and it will assign document.referrer as s.referrer value. For avoiding this you can assign the value of as s.referrer="Empty" or s.referrer="none"(string value to be assigned) if s.Util.getQueryParam("ref"); value is null/empty or ' '.

      What if I use the adobe_mc_ref parameter

      In test it looks like it works, any experience with it for this scenario?
