Using Content Advisor to block specific PARTS of a site

[zephyran]

I have some computers that are locked down to start on a certain website (let's call it

http://www.catalogsite.com)

and not allow use of the address bar. However, there is a link on that site (I have no control over the site's content) that allows users to access a different website that contains links to the most popular search engines. I do not want to allow any general Internet browsing on this machine, only browsing through the content of that specific site.

I need to be able to block the default page on that specific link (the link goes to a site URL, let's call it

http://www.somesite.com),

but allow access to directories inside that site (i.e.

http://www.somesite.com/location_information)

that are accessed by separate links in the

http://www.catalogsite.com

site. I have so far been unsuccessful in getting Content Advisor to do this. Is there a way to get it do do that?
