title: Parsing HTTP header 'set-cookie' with HTTParty
body: <p>I'm using HTTParty for making HTTP requests and for using REST APIs. Now I want to re-use cookies set by a login page I called via POST.</p>
  
  <pre><code>class SomeImporter
    include HTTParty
  
    def self.login
      response = self.post('https://www.example.com/login', :query =&gt; {:user =&gt; 'myusername', :password =&gt; 'secret'})
      self.default_cookies.add_cookies(response.header['set-cookie'])
      self.get('https://www.example.com/protected')
    end
  end
  </code></pre>
  
  <p>The cookies are not set correctly with this code.
  How to parse the 'set-cookie' header given by HTTParty correctly and set the cookies for next request?</p>
