Hi Nikhil,

It is definitely possible to block websites on the ASA. Here is a method of blocking it .Though the filtering of https websites based on URLs is not possible. Since the https traffic is encrypted we cannot inspect HTTPS traffic.

Using Regular Expressions

Also this document is a very interesting read https://supportforums.cisco.com/docs/DOC-1268

I hope this helps.

Thanks,

Namit
