RE: What would be the difference between these two class-maps

Please clarify
So if we were to match the host and url we would need a match-all statement in the class-map one for the host and one for the directory ?
Like the example below
www.yahoo.com/finance

class-map match-all TEST
match protocol http host www.yahoo.com
match protocol http url "finance"

Correct, even though you specify anything after the /, nbar strips that and
only matches the host portion of your string so with your second statement
you would match anything from www.cisco.com regardless of what directory it
came from.

From the doc url

Host specification is identical to URL specification. NBAR performs a
regular expression match on the host field contents inside an HTTP packet
and classifies all packets from that host. For example, for the URL
www.cisco.com/latest/whatsnew.html, include only www.cisco.com.
