after hours of searching for a solution here is a problem..

i have a parked domain (parkeddomain.com ) which points to a subdirectory (parkeddomain) . Drupal installation is in the subdirectory.

on firefox everything works fine, grin, of course

on IE 6,7,8 same issue

when trying to login at
homedomain.com/parkeddomain/drupal works fine

when loging in at
parkeddomain.com/drupal appears that nothing happens. the screen refreshes to the user login state, but checking the log files shows that the session did open...
