HOW TO SCAN/CRACK OVER A PROXY
------------------------------
The environment variable HYDRA_PROXY_HTTP defines the web proxy (this works
just for the http/www service!).
The following syntax is valid:
  HYDRA_PROXY_HTTP="http://123.45.67.89:8080/"
For all other services, use the HYDRA_PROXY_CONNECT variable to scan/crack
via a web proxy's CONNECT call. It uses the same syntax. eg:
  HYDRA_PROXY_CONNECT=proxy.anonymizer.com:8000
If you require authentication for the proxy, use the HYDRA_PROXY_AUTH
environment variable:
  HYDRA_PROXY_AUTH="the_login:the_password"

hydra.exe  -p pass.txt -l logins.txt -s 80 ip_address http-get HYDRA_PROXY_HTTP
="http://123.45.67.89:8080/"

$ export HYDRA_PROXY_HTTP="http://123.45.67.89:8080/"
$ export HYDRA_PROXY_CONNECT=proxy.anonymizer.com:8000
$ export HYDRA_PROXY_AUTH="the_login:the_password"
