Ok, here is what I did.
I created a URL set of the sites that I need to allow.
I created Rule 1 as follows:
ACTION: Allow (and log)
PROTOCOLS: HTTP/HTTPS
FROM: Internal
TO: (my URL Set)
USERS: (my specific user)
SCHEDULE: Always
CONTENT TYPES: All content type
I created Rule 2 as follows:
ACTION: Deny (redirect to custom page and log)
PROTOCOLS: All Outbound
FROM: Internal
TO: External
USERS: (my specific user)
SCHEDULE: Always
CONTENT TYPES: All content type
SSL sites are still not allowed, so what do I need to change to allow
this user to access the necessary SSL sites?
