[TYPO3-core] RFC #11968: Sporadic random Backend Logoffs / Add X-UA-Compatible flag

[Steffen Gebert]

Hey all,

This is a SVN patch request.

Type: Bugfix

Branches: 4-3, trunk

BT ref: http://bugs.typo3.org/view.php?id=11968

Problem:
IE8 has a pathetic way to switch from its normal mode to the Compatibilty  
mode (aka. IE7): All cookies are lost and so all sessions are lost.
This results in a aprupt BE logout, as soon as any Markup/JS error causes  
IE8 to switch to the Compatibility mode.

Solution:
Add
  <meta http-equiv="X-UA-Compatible" content="IE=8" />
to prevent the switch to the compatibility mode. BE works with IE8 and so  
we can do this!

Regards
Steffen
