-- @usage nmap -p80 --script http-mobileversion-checker.nse <host>
--
-- This script sets an Android User-Agent header and checks if the request
-- will be redirected to a page different than a (valid) browser request
-- would be. If so, this page is most likely to be a mobile version of the
-- app.
--
-- @args newtargets If this is set, add any newly discovered hosts to nmap
--                  scanning queue. Default: nil
--
-- @output
-- PORT   STATE SERVICE REASON
-- 80/tcp open  http    syn-ack
-- |_ http-mobileversion-checker: Found mobile version: https://m.some-very-random-website.com (Redirected to a different host)
