Use TCPDUMP to Monitor HTTP Traffic
1. To monitor HTTP traffic including request and response headers and message body:

tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'

2. To monitor HTTP traffic including request and response headers and message body from a particular source:

tcpdump -A -s 0 'src example.com and tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'

3. To monitor HTTP traffic including request and response headers and message body from local host to local host:
