title: How do I configure WEBrick to use an intermediate certificate with HTTPS?
body: <p>I am currently using the following options in my Rails app to enable HTTPS with WEBrick:</p>
  
  <pre><code>{
      :Port =&gt; 3000,
      :environment =&gt; (ENV['RAILS_ENV'] || "development").dup,
      :daemonize =&gt; false,
      :debugger =&gt; false,
      :pid =&gt; File.expand_path("tmp/pids/server.pid"),
      :config =&gt; File.expand_path("config.ru"),
      :SSLEnable =&gt; true,
      :SSLVerifyClient =&gt; OpenSSL::SSL::VERIFY_NONE,
      :SSLPrivateKey =&gt; OpenSSL::PKey::RSA.new(
          File.open("certificates/https/key.pem").read),
      :SSLCertificate =&gt; OpenSSL::X509::Certificate.new(
          File.open("certificates/https/cert.pem").read),
      :SSLCertName =&gt; [["CN", WEBrick::Utils::getservername]]
  }
  </code></pre>
  
  <p>How would I go about specifying an intermediate certificate?</p>
