    Fix Description: The old DSGW used to support GET and POST at the same time.  This does not work anymore since moving to use adminutil.  The solution is to use POST style form arguments with post actions - so lang?file=alert.html becomes <input name=file value=alert.html> inside of a FORM POST.
    Platforms tested: RHEL5
