HTTP-ProxyTest version 0.11 =========================== Robots that send comment spam are often hidden behind anonymous open proxy servers. You can use HTTP::ProxyTest to look for open proxies on-the-fly and prevent such spam robots from submitting their crap. The module is particularly useful if you don't want to bother your web site visitors with CAPTCHAs etc. HTTP::ProxyTest tests certain ports of REMOTE_ADDR that are often used for anonymous open proxies, and denies access if an open proxy is found, i.e. it responds with status "403 Forbidden" and exits. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES This module requires the libwww-perl set of modules. It's strongly recommended that the Nmap security scanner is available.
