We have some (not all) Internet Explorer 8 - which looses the session
"shortly" after login to either FE og BE. I do not believe it is related to
After some investigation, it is quite clear that the session expires after
the first Ajax call. If no Ajax call - no problem. You are able to log into
e.g. the BackEnd of a new TYPO3 version 4.2. But after hitting some
functionality using an Ajax call, you will on the next request find yourself
no longer logged in. This could e.g. be the Clear Cache buttons. It seems
likes it works - but on the next request you are no longer welcome :)
Many different (all?) TYPO3 versions seems affected. No problem observed in
other version of IE (6,7) or FF or any other browser. Only some IE8 users is
Same behavior in FE. Also with different types of Ajax implementations
(libraries). It seems closely related to TYPO3 - since many other
applications is with great success using Ajax.
The last really really puzzling observation in this regard - is that if I
activate the "InPrivate-browsing" feature of IE8, everything seems to work
In all situations - analyzing network traffic with makes me conclude that IE
is accepting the fe_typo_user cookies that it is asked to use. After
initially setting the cookie - all subsequent requests, including the coming
Ajax request, has the new cookie value. Session will fail on the first Ajax
Request. eID related ??
Any suggestions or solutions? Someone who can replicate this behavior?
Thank you in advance.
