I tried to run the code of the site but it gives me error
   require 'net/http'

    proxy_addr = 'vsnlproxy.iitk.ac.in'
    proxy_port = 3128
            :
    Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com') {|http|
        # always connect to your.proxy.addr:8080
            :
    }
Error:
  c:/ruby/lib/ruby/1.8/uri/common.rb:432:in `split': bad URI(is not
URI?): (URI::
InvalidURIError)
        from c:/ruby/lib/ruby/1.8/uri/common.rb:481:in `parse'
