Can the Super Search URL use FTP?

In the configuration file can i set this super_search.url = to be ftp://userid:password@ftplocation.com and have it work?

Also i have the T46G on the latest firmware and have not been able to get the favorites file to work.

<root_favorite_set>
<item id_name="localdirectory" display_name="Local Directory" priority="1" enable="1" />
<item id_name="history" display_name="History" priority="2" enable="0" />
<item id_name="networkcalllog" display_name="Network CallLog" priority="3" enable="0" />
<item id_name="remotedirectory" display_name="Remote Phone Book" priority="4" enable="1" />
<item id_name="ldap" display_name="LDAP" priority="5" enable="0" />
<item id_name="broadsoftdirectory" display_name="Broadsoft Directory" priority="6" enable="0" />
</root_favorite_set>

I am trying to get the remote directory enabled. I have a 1 there. I can see the file sending but nothing updates. what am i doing wrong here?
