How do I configure WEBrick to use an intermediate certificate with HTTPS?

Question

I am currently using the following options in my Rails app to enable HTTPS with WEBrick:

{
    :Port => 3000,
    :environment => (ENV[\'RAILS_ENV\'] |

I managed to find an answer after an extra hour of googling for keywords. Here is the option to define an intermediate certificate:

:SSLExtraChainCert => [
    OpenSSL::X509::Certificate.new(
      File.open("certificates/intermediate.crt").read)]

Note that the option requires an Array object, allowing to you include multiple certificates if needed.
