Cisco Security :: Block Access To Some Websites On 887 Router?

I went through all discussions regarding how to block access to some web sites. And I was trying to implement them but it didn't work. I've used 887G-3G-K9 router and UC540, and I'm not sure if it's possible to do that on them or I need to get a license for that or to buy  ASA. How can I check that URL blocking is available feature on those devices?
 
I've used 2 methods:

1) ACL
 
2) class-map and policy-map
 
class-map match-any http
match protocol http url "*facebook.com*"
match protocol http url "*www.facebook.com*"
