#!/usr/bin/python
# Cross-Site Tracer by 1N3 v20150224
# https://crowdshield.com
#
# ABOUT: A quick and easy script to check remote web servers for Cross-Site Tracing. For more robust mass scanning, create a list of domains or IP addresses to iterate through by running 'for a in `cat targets.txt`; do ./xsstracer.py $a 80; done;'
#
# USAGE: xsstracer.py <IP/host> <port>
#
