Create a Bro script file containing a module that will detect when an HTTP request header has a host value that is present in a list of interesting domains. You will place the domain you selected in this list. When one of these domains is detected you will use the notification framework to write out a notice. The script file should have a .bro extension. You can test the script by running Bro against your PCAP file and providing it as the last argument as described in lecture.
