#   Bash Web Requester

#   License: GPL v2  
#
#   takes 2 arguments:
#   one is a file with a list of URLs (url like http://site.com/test.asp)
#   second is file with regexp compatible pattern that checks page content for matched keywords
#   
#   E.g If you request URL which contains string like 'require_once' in URL response, which is defined in 2nd argument file
#       then the url is likely vulnerable to internal path disclosure
#   
#   Run an example so that you can get it better
#   req-urls.txt payload-res-pattern.txt
