Proxy

Creates an HTTP proxy class which behaves like Net::HTTP, but performs all access via the specified proxy.

The arguments are the DNS name or IP address of the proxy host, the port to use to access the proxy, and a username and password if authorization is required to use the proxy.

You can replace any use of the Net::HTTP class with use of the proxy class created.

If p_addr is nil, this method returns self (a Net::HTTP object).

# Example
proxy_class = Net::HTTP::Proxy('proxy.example.com', 8080)

proxy_class.start('www.ruby-lang.org') {|http|
  # connecting proxy.foo.org:8080
}

You may use them to work with authorization-enabled proxies:

proxy_host = 'your.proxy.example'
proxy_port = 8080
proxy_user = 'user'
proxy_pass = 'pass'

proxy = Net::HTTP::Proxy(proxy_host, proxy_port, proxy_user, proxy_pass)
proxy.start('www.example.com') { |http|
  # always connect to your.proxy.example:8080 using specified username
  # and password
}

Note that net/http does not use the HTTP_PROXY environment variable. If you want to use a proxy, you must set it explicitly.
