Hi Experts,
This is in reference to ZBFW and NBAR URL Filtering
What is the difference between Header field inspection and URL inspection in Zone based Firewall. After reading the Cisco documents I learned that,
URL inspection is used as below:
parameter-map type regex uri_regex_cm
pattern.*cmd.exe
pattern.*gambling
Header field inspection is used as below:
parameter-map type regex ref_regex
pattern \.delfinproject\.com
pattern \.looksmart\.com
For me both seems to do the same job.
I know I have understood this wrong way.
Can you please educate me
Thanks in advance
Sairam
