# Monitor HTTP requests being made from your machine with a one-liner..
# Replace "en1" below with your network interface's name (usually en0 or en1)
sudo tcpdump -i en1 -n -s 0 -w - | grep -a -o -E "Host\: .*|GET \/.*"
# OR.. to be able to use as "httpdump" from anywhere, drop this into ~/.bash_profile:
# (again replace "en1" with correct network interface name)
alias httpdump="sudo tcpdump -i en1 -n -s 0 -w - | grep -a -o -E "Host\: .*|GET \/.*""
# All the above tested only on OS X.
