Hi, great work on this solution!
I am wondering if it is possible to have Google Analytics for the links which will be then redirected?!
Does anyone have a solution for this or can point me in the right direction?

My solution is to use Google tag manager to set a "goal" to capture click url that contains "go" (just treat it as an external link), otherwise Google analytic alone could not capture it because you have no Google Analytic code in the /go url. Correct me if I am wrong.

Great work. Any idea how I block direct browser access to the redirects.txt file via htaccess?

Currently all my aff urls are accessible via https://my-site/link/redirects.txt
