Checking HTTP Status Code in Selenium

Question

Can I in selenium get the HTTP status code?

E.g. so I can test that if the browser requests /user/27 and no user with ID=27 exists, an HTTP 404 is returned?

My primary interest is Selenium RC, but if someone knows the answer for "normal" selenium, I can probably easily translate it into RC.

This might not be the best use of Selenium for this type of test. There is unnecessary need to load a browser when you could do and have a faster running test

    [Test]
    [ExpectedException(typeof(WebException), UserMessage = "The remote server returned an error: (404) Not Found")]
    public void ShouldThrowA404()
    {
        HttpWebRequest task; //For Calling the page
        HttpWebResponse taskresponse = null; //Response returned
        task = (HttpWebRequest)WebRequest.Create("http://foo.bar/thiswontexistevenifiwishedonedayitwould.html");
        taskresponse = (HttpWebResponse)task.GetResponse();
    } 

If your test is redirecting to another page during a 404 Selenium could check the final page has what you expect.

You probably want to check out the captureNetworkTraffic() call. Right now it only works reliably with Firefox, unless you manually set up IE/Safari/etc to proxy traffic through port 4444.

To use it, just call selenium.start("captureNetworkTraffic=true"), and then later on in your script you can call selenium.captureNetworkTraffic("...") where "..." is "plain", "xml", or "json".
