WebRequest - Prevent redirection

I am using a WebRequest to read an HTML site. The server seems to be redirecting my request.

My Code is similar to the following:

    String URI = "http://www.foo.com/bar/index.html"
    WebRequest req = WebRequest.Create(URI);
    WebResponse resp = req.GetResponse();
    StreamReader sr = new StreamReader(resp.GetResponseStream());
    String returnedContent = sr.ReadToEnd();

When I check the content of the returnedContent it contains the content from a redirection like "http://www.foo.com/FOO_BAR/index.html". I am sure my requested URL exists since it is part of the recieved response (as an IFrame).

Is there a way to prevent the WebResponse to be redirected and get the content of the requested url?

UPDATE

Setting req.AllowAutoRedirect = false leads to a 302 Found state code, but does not deliver the acutal content.

Some more details: My requested url was http://www.foo.com/bar/index.html the content I receive is located in http://www.foo.com/FOO_BAR/index.html

The response looks similar to this:

<body>
    <div>
        <iframe src="/foo/index.html"></iframe>
    </div>
</body>

I know this is a rather old post, but thought I'd share what I found in my particular situation...

I was trying to access a site to see if specific content is available. I found that it kept redirecting away from the site I requested to a local version of the site. I noticed some cookies that were responsible for the redirect. If anyone else runs into the same issue, it's possible that there's a cookie or some other request header that you can play with to prevent the redirect away from your intended target.

In my case all I had to do was something like this:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
//whatever other headers you need...
request.Headers.Add(HttpRequestHeader.Cookie, "ipRedirectOverride=true");

Note that this is just an example, your cookie name / value may be different

You can use HttpWebRequest’s AllowAutoRedirect property:

…
var req = (HttpWebRequest)WebRequest.Create(URI);
req.AllowAutoRedirect = false;
…
