BUG MIGRATED FROM SOURCEFORGE http://sourceforge.net/tracker/index.php?func=detail&aid=1009202&group_id=34373&atid=411192 Originally submitted by bigmamacare (bigmamacare) 2004-08-14 16:41 This obviously does not impact any function but it is annoying because one's not shure about logon status. This can be observed in any browser (Firefox/Mozilla, IE and so on). MySQL Version: MySQL 3.23.57-log running on Linux 2.4.25_pre7-gss-r3 using an Apache/1.3.27 (Unix).
The session cookie should remain on logout, so it ought to be possible to slip another cache expiration timestamp into the session. This will only last until the browser is closed, however.
*** Bug 74 has been marked as a duplicate of this bug. ***
May this problem caused by <MediaWiki>/includes/SkinTemlate.php: I think the values should be read from cookie. Or the global variable $wgUser should be updated. from Line 417: if( $wgShowIPinHeader && isset( $_COOKIE[ini_get("session.name")] ) ) { $personal_urls['anonuserpage'] = array( 'text' => $this->username, 'href' => &$this->userpageUrlDetails['href'], 'class' => $this->userpageUrlDetails['exists']?false:'new' ); ........
(In reply to comment #3) > May this problem caused by <MediaWiki>/includes/SkinTemlate.php: What that bit does is to show a generic header (just the login link) if you don't have a session or login active, so that the page output can be cached and served to all other visitors who don't have a session or login active. If you are logged in or have a session active (eg, you're logged in, OR you've visited the login page, OR you've edited something), then it will show you user name (IP address if you're not logged in) and talk page. This is unrelated to the problem of this bug, which is that the logged-in page view is retained in the local browser cache after logout.

Yes, I also found out that. I can fix this display problem by the following workaround, but I am not sure if it is correct to the execution of the whole MeidaWiki system. I just disabled the cache in returnToMain method, this works on my FreeBSD, I did not test it on Windows. //<MediaWiki>/includes/OutputPage.php function returnToMain( $auto = true, $returnto = NULL ) { global $wgUser, $wgOut, $wgRequest; //added by Junhua Wang start $this->enableClientCache( false ); //added by Junhua Wang end ......

And it seems IE works well with this workaround but Firefox1.0 not. If I want make all the browsers compliant, the line added by me should be moved to method "output" in OutputPage.php, and I don't think it is a good solution to this problem... :(
(In reply to comment #5) > $this->enableClientCache( false ); This would tell the browser not to cache the page which says "You are now logged out." etc, while having no effect on anything else. Since it's an uncacheable special page and not one you'd revisit, I don't think this would actually accomplish anything.
Fixed in CVS: set cookie with logged in and log out timestamp, then check them when checking If-Modified-Since.
