When I am trying to login to my site by calling /authenticate method, I am receiving sessionid=x inside cookies. However for next req eg: /getUserRole, the the session id is not the same. for eg: sessionid=y. We are not modifying any cookie parameter at front end. This behavior is only occurring on ios devices ( ipad, mobiles ). For mac machine its working on google chrome but not not safari.
The session id validation is done in drupal. Also this is not working for a particular front end code base. For different front end code base its working fine. The only difference in that other frond end codebase is few html and css changes.
