Steps to reproduce:

 # When using HTTP radius authentication and want to do a apache logout, set these rewrite rules:
 ## RewriteCond %\{REQUEST_URI} ^/index.php$
RewriteCond %\{QUERY_STRING} ^reconnect=1$ [NC] 

RewriteRule ".*" "http://%\{HTTP_HOST} [R=302,L]

1. Clicking signout works, when signing in again asks for user/password
2. However on some pages, a weird behaviour is seen until the browser is closed or URL is reopened from the address bar

Result:
See screenshot

Expected:
See screenshot....
