Can anyone give 2-3 good reasons for doing url filtering using the CSC instead of MPF? Is there a limit on the number of entries in the list? How about other resource or process hits to the ASA?

This forum might not be the best place to ask a URL filtering questions. The IDS/IPS aspects of the ASA are usualy as deep as the discussions go into the ASA chassis here. You might try asking in the Firewall forum.

Here are some reasons:


1) The ASA can only have 4GE interface card, AIP -SSM (IPS) or the CSC at once. If you need the other two the only remaining choice is MPF or external server


2) Cost! The CSC costs money, and maybe a particular customer requires just to block a handful of websites, the CSC would be over-kill there.
