How to test manually

1. Install the Referer Modifier addon https://addons.mozilla.org/en-US/firefox/addon/referer-modifier/
2. Configure it so the Referer header is removed when the domain target is "Same domain"
3. Go to AgentJ, select several messages and perform a batch action on them
4. Verify that you're redirected back to the previous page
5. Change the current locale, and check that it works too
6. Go to the list of users and change the number of paginated items, and check that it works too
7. Remove the addon and perform the tests again
