	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:

	function mapper(row, emit) {
	if(row.comment) {
	keywords = row.comment.split(' ');
	for(var i=0; i<keywords.length; i++) {
	emit({keyword: keywords[i], count: 1});
	}
	}
	}

	function reducer(row, emit) {

	import boto3
	print(boto3.client('sts').get_caller_identity()['Account'])
