TYPO3 Core

Currently I run several sites on one typo3 installation (version 4.3.1). A frontend user can perform the login but once he accesses an other page his identification gets lost.

Reading around I found that the compatibility mode might break the session. Therefore I added <meta http-equiv="X-UA-Compatible" content="IE=8" /> to the page header and veryfied the page to be valid in html, css and js.

When deleting the session cookies (through developer tool bar and not closing the browser, hence session) the auto logoff disapears and everything works fine.

As well I observed that the cookie domain isn't denominated correctly. In firefox the domain value is .venandar.com where in ie8 one just finds .com.

As well I read that upen setting [SYS][cookieDomain] the problem might disapear as well but using this parameter on a multi domain installation doesn't seem to be aproriate.

sr_feuser_register 2.5.8 is installed as well
