Selectively blocking internet access on windows, based on a pattern in the requested URL?

Question

I need to block access by a certain Windows program to specific paths of a web site, but not to other paths on that site. Therefore I think using the hosts file won't be helpful for that.

Is there any way to block access to URLs matching a regular expression or even just those containing a specific substring?

Thanks!

Privoxy can do this, set it as proxy of Internet Explorer (or your application if it allows you to).
