HttpWebRequest 403 Error

Question

I am new to C # and have a requirement to get the url from C #. In most cases, it works fine, but in one case it throws an error. url is as follows http://whois.afrinic.net/cgi-bin/whois?searchtext=41.132.178.138

Error:

An exception was made in the HTTP request for the URL: http://whois.afrinic.net/cgi-bin/whois?searchtext=41.132.178.138 The remote server returned an error: (403) Forbidden.

My code is equal

void MyFUnction(string url)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

    request.UserAgent = ".NET Framework Test Client";
    request.ContentType = "application/x-www-form-urlencoded";
    Logger.WriteMyLog("application/x-www-form-urlencoded");


    // execute the request
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    // we will read data via the response stream
    Stream resStream = response.GetResponseStream();

    string tempString = null;
    int count = 0;
    do
    {
        // fill the buffer with data
        count = resStream.Read(buf, 0, buf.Length);

        // make sure we read some data
        if (count != 0)
        {
            // translate from bytes to ASCII text
            tempString = Encoding.ASCII.GetString(buf, 0, count);
            if (httpData == null)
                httpData = tempString;
            else
                httpData += tempString;

        }
    }
    while (count > 0); // any more data to read?
}

Answer 1

Delete the line ContentType.

request.ContentType....

You do not make a message in the form, but only get the page using "GET".

request.Method = "GET"; //this is the default behavior

Also set the Accept property to "text / html".

request.Accept = "text/html";

Answer 2

request.Accept = "text/html";
