read_nonblock': end of file reached (EOF Error)

I have written a program to consume a Restful Service from yahoo, and
I am landed with this error.

I am using Net/HTTP library for this,

My program is as follows

require 'net/http'

APPLICATION_ID = 'XIM4jgY6YIrOoB'
YAHOO_WEB_SERVICE_SEARCH_URL = 'http://search.yahooapis.com/
WebSearchService/V1/webSearch'
query = 'world cup 2011'
results_limit = 10

proxy_addr = 'MyProxy'
proxy_port = 80
proxy_name = "MyName"
proxy_pass = "MyPassword"
path = "?appid=#{APPLICATION_ID}&query=#{URI.encode(query)}
&results=#{results_limit}"

Net::HTTP::Proxy(proxy_addr, roxy_port, proxy_name,
proxy_pass ).start( YAHOO_WEB_SERVICE_SEARCH_URL ) do |http|
  response = http.get(path)
  puts response.body
end

When I run this program, I am getting this error on which I have no
clue, but the same works with browser

/usr/local/lib/ruby/1.9.1/net/protocol.rb:135:in `read_nonblock': end
