Stefan Wendrich1709160263 Posted May 6, 2021 Share Posted May 6, 2021 Hello, we updated our gateway from 12.1 to 13.0 build 79.64. After that, the login through modern browsers like chrome or firefox is not working anymore. Login through internet explorer works. After some troubleshooting, we found out, that the expression for the receiverweb policy is "http.REQ.HEADER("User-Agent").CONTAINS("CitrixReceiver").NOT && http.REQ.HEADER("Referer").EXISTS" We removed the part behind && so that the new expression is "http.REQ.HEADER("User-Agent").CONTAINS("CitrixReceiver").NOT" After that change, the login works. Why is the referer not detected with modern browsers like chrome? And why after the upgrade to 13.0 ? With 12.1 all was working fine. Link to comment Share on other sites More sharing options...
Johan Parlevliet Posted July 16, 2021 Share Posted July 16, 2021 It is a pitty that nobody has an answer to this question.

I did research on myself and updated the headers in a list. In my experience I'm always trying to NOT use the "Referer" header as it's outdated. Checkout my post on Blog Hope this helps!

Joe Marriott Posted December 15, 2021 Share Posted December 15, 2021 seeing this too after updating from 12.1 to 13.0. Does anyone have a Citrix ticket open on this? Link to comment Share on other sites More sharing options...
