IP Proxy Problem

hi all can anyone guide me
i have a little problem here with my MT box
i want use a proxy for web cache and using
that proxy to limit the access (people who
can access inet and dont have access)

and i already use IP Proxy for limit the access
but i have problem when someone access
the https/ssl site, why the access is deny???
how can i use IP Proxy for access https (443) ??
please help me…

thanks

proxy in MT does not support https.

in that case, do you have sugestion for my network…??
i have 500 user on network but i only giving an internet
to 50 - 60 user only…
which method i can use to limit the user access to inet…??

limit user to inet in here is to who i give the inet access
not limit the people who connect to inet…
if some user have righ to access the inet, then the user
is freely to use that inet.

Thanks and sorry for my bad english.
