[c-nsp] Cisco asa5550 url filter

[Bunny Singh]

Hi, 
 
We are using Cisco asa5550, and i want to put a url based acl/filteration for the particular client.
 
We have one client on inside interface who needs the access of www.youtube.com only(outside interface) and to restrict the same we are not able to restrict through IP acl's as Youtube ip's are changing periodically.
 
So is it any way to put a http url filter to open only a single desired site and else will be denied.
 
Regards
