title: VCR runs only one time for integration test in capybara with selenium webkit
body: <p>I am using Rspec with Capybara running the integrational tests using VCR gem to mock stub the api requests.
  I am facing a vary weird kind of an issue. The test runs successfully for the first time and creates the yaml file for saving the requests and their responses.
  But if I run test again after yaml file is created then it runs into an issue and shows the following issue :-</p>

    1) AffiliateSignUpProcesses Sign up using affiliate link should create User/Affiliate/AffiliateToken and Conversion when user is created
       Failure/Error: visit pricing_path(:aid =&gt; 'this_is_sample_value')
       VCR::Errors::UnhandledHTTPRequestError:
  
  
         ================================================================================
         An HTTP request has been made that VCR does not know how to handle:
           GET http://127.0.0.1:58021/__identify__
  
         VCR is currently using the following cassette:
           - /home/pcname/appname/selenium-error/fildername/appaname/cassettes/acceptanceTest/AffiliateSignUpProcess.yml
           - :record =&gt; :once
           - :match_requests_on =&gt; [:method, :uri]
  
         Under the current configuration VCR can not find a suitable HTTP interaction
         to replay and is prevented from recording new requests. There are a few ways
         you can deal with this:
  
           * If you're surprised VCR is raising this error
             and want insight about how VCR attempted to handle the request,
             you can use the debug_logger configuration option to log more details [1].
           * You can use the :new_episodes record mode to allow VCR to
             record this new request to the existing cassette [2].
           * If you want VCR to ignore this request (and others like it), you can
             set an `ignore_request` callback [3].
           * The current record mode (:once) does not allow new requests to be recorded
             to a previously recorded cassette. You can delete the cassette file and re-run
             your tests to allow the cassette to be recorded with this request [4].
           * The cassette contains 64 HTTP interactions that have not been
             played back. If your request is non-deterministic, you may need to
             change your :match_requests_on cassette option to be more lenient
             or use a custom request matcher to allow it to match [5].
