Question

When i trying to load html from server by https, it returning an error code 500: but when i open same link in browser it works fine: is there any way to do this? I’m using Webclient and also sending a useragent information to the server:

HttpWebRequest req1 = (HttpWebRequest)WebRequest.Create("mobile.unibet.com/";); 
req1.UserAgent = @"Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5";
var response1 = req1.GetResponse();
var responsestream1 = response1.GetResponseStream();

Answer 1

David is correct, this generally happens when the server is expecting some headers that is not passed through, in your case Accept

this code works now

string requestUrl = "https://mobile.unibet.com/unibet_index.t";
var request = (HttpWebRequest)WebRequest.Create(requestUrl);
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.UserAgent = "//Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";

using (var response = request.GetResponse() as HttpWebResponse)
{
 using (var sr = new StreamReader(response.GetResponseStream()))
 {
           var responsestring = sr.ReadToEnd();
       if (!string.IsNullOrEmpty(responsestring))
       {
    Console.WriteLine(responsestring);
           }
  }
 }
