Backbone is connecting via HTTP(s) to Jira. At the moment Backbone sends HTTP authentication information in every request it's performing. However, this leads in some scenarios to lots of sessions and may affect the performance of the overall Jira system.
Especially systems with lots of synchronized issues and synchronizations are facing this problem.
Backbone's mechanism to reuse an HTTP session should be improved so that it works for all Jiras. In addition, by using a session based authentication, the number of necessary authentications can be improved as well.
