title: Undefined method 'request_uri'
body: <p>I am working with the <a href="https://github.com/w2davids/Shopsense" rel="nofollow">Shopsense Ruby Gem</a> however I am unable to use the gem.  Making requests exactly as in the <a href="https://github.com/w2davids/Shopsense/blob/master/test/test_shopsense.rb" rel="nofollow">test</a> I receive the following error:</p>
  
  <pre><code>/Users/rudolph9/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:455:in `block in get_response': undefined method `request_uri' for #&lt;URI::Generic:0x007fd5b3a66810&gt; (NoMethodError)
      from /Users/rudolph9/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:745:in `start'
      from /Users/rudolph9/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:454:in `get_response'
      from /Users/rudolph9/.rvm/gems/ruby-1.9.3-p0/gems/Shopsense-0.1.1/lib/Shopsense.rb:76:in `do_search'
      from test_shopsense.rb:10:in `&lt;main&gt;'
  </code></pre>
  
  <p>However, the test works fine if I clone the repository, modify the test and require the source directly as follows: </p>
  
  <pre><code>1 #!/usr/bin/env ruby¬                                                                                                                                                       
  2 require 'rubygems'¬
  3 #require 'Shopsense'¬
  4 require '../lib/shopsense.rb'¬
  .
  .
  .
  </code></pre>
  
  <p>What is the issue when using the gem it self??</p>
