okay great, so 2 questions.. would the following work? and am I correct in assuming that only those IP addresses listed in "urlfilter' will be subject to the filtering? and all others will be permitted?
access-list urlfilter permit tcp host 192.168.1.50 any eq 80
access-list urlfilter permit tcp host 192.168.1.51 any eq 80
access-list urlfilter permit tcp host 192.168.1.52 any eq 80
access-list urlfilter permit tcp host 192.168.1.53 any eq 80
class-map httptraffic
match access-list urlfilter
regex domainlist1 "\.facebook\.com"
regex domainlist2 "\.twitter\.com"
regex domainlist3 "\.myspace\.com"
regex domainlist4 "\.youtube\.com"
class-map type regex match-any DomainBlockList
match regex domainlist1
match regex domainlist2
match regex domainlist3
match regex domainlist4
class-map type inspect http match-all BlockDomainsClass
match request header host regex class DomainBlockList
policy-map type inspect http http_inspection_policy
class BlockDomainsClass
reset log
policy-map inside-policy
class httptraffic
inspect http http_inspection_policy
service-policy inside-policy interface inside
