Question

The following code fails with a 400 bad request exception. My network connection is good and I can go to the site but I cannot get this uri with HttpWebRequest.

private void button3_Click(object sender, EventArgs e) {     WebRequest req = HttpWebRequest.Create(@'http://www.youtube.com/');     try     {         //returns a 400 bad request... Any ideas???         WebResponse response = req.GetResponse();     }     catch (WebException ex)     {         Log(ex.Message);                     } } 

Answer 1

First, cast the WebRequest to an HttpWebRequest like this:

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(@'http://www.youtube.com/'); 

Then, add this line of code:

req.UserAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)';
