Scenario:
- WebEdit functionality is widely used by FirstSpirit editors
- they often try to work in different projects at the same time
- in general they use up-to-date browser versions offering multi-tabbing in one browser instance
![multitab_browsing.jpg multitab_browsing.jpg](/t5/image/serverpage/image-id/4124i3DD6F6C0AC8340A4/image-size/large?v=v2&px=999)
Environment:
- FS 3.1, FS 4.0, FS 4.1, FS 4.2 R2, FS 4.2 R4, FS 5.0
- FirstSpirit WebEdit
- Multi-tab enabled browsers like FireFox, >IE6, Opera, etc.
Problem description:
- multi-tab browsers share sessions (JSESSIONID cookie) between different tabs
- opening multiple FirstSpirit projects in different browser tabs and working on them in turn
lead to error messages and data lost in all tabs simultaneously - "not connected" error messages appear in the Servlet Container logs (Tomcat or Jetty)
endlessly (see below)
