Tracking in twitter urls & twitter's "copy url"

[06000208]

The s query parameter identifies which device you're on (s=20 is the destkop website, s=19 is the android twitter mobile app) while t is an unknown query parameter very likely used for tracking, even when signed out. This occurs when you click "Copy link to Tweet" in the twitter UI.
