In Windows Vista 32-bit and 64-bit machines, if you use multiple tabs in the same browser to access protected resources, the browser cache is not cleared from the registry entry, even if you selected
in the Exit page. This issue occurs if Internet Explorer versions earlier than 7.0 are used with the Add Tab plug-in or if Internet Explorer 7.0 is used to connect to SSL VPN, and the protected resources are accessed in the other tabs of the same resource. To clear the cache, browse to the following location and manually delete the files:HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs
