title: Authentication headers using Rest Client Ruby Gem
body: <p>I have already created a basic authentication key, now I am just trying to utilize it. I have tried a few different variations, but none seem to show Authorization in the request headers.</p>
  
  <pre><code>$auth = 'Basic cmFtZXNoQHVzYW1hLmNvbTpyYW1lc2h1JEBtcA=='
  
  
  @response = resource.post('Authorization' =&gt; $auth)
  nor
  @response = resource.post(:authorization =&gt; $auth)
  nor
  @response = resource.post(:Authorization =&gt; $auth)
  nor
  @response = resource.post(:content_type =&gt; :json, :accept =&gt; :json, :headers =&gt; { 'Authorization:' =&gt; $auth })
  </code></pre>
  
  <p>Unfortunately I am not finding a lot of info in the rdoc that can help me solve this. Does anyone have experience adding auth headers using the Rest Client gem?</p>
