title: Content-Length or Chunked Encoding cannot be set for an operation that does not write data what should i do?
body: <p>I try to access a specific page on the site and pull it out of information.
  I did <code>GET</code> request to the homepage and I get response status code ==OK 
  then I do another <code>GET</code> request to the page that contains the <code>Json</code> I want to retrieve) and the response status code == OK.</p>
  
  <p>Now I want to retrieve the information so I do get request for the resource (another URL that the last page load)
  And I get the error at this line:</p>
  
  <pre><code>HttpWebResponse oHttpResponseIndicesApiUrl = (HttpWebResponse)oHttpRequestIndicesApiUrl.GetResponse();
  </code></pre>

  <p>I set all the headers Just like the get request inside the chrome Inspect -> Network Tab -> choose the URL that i wanna(there i can see the get request headers)</p>
  
  <p>this is the code that i run:</p>
  
  <pre><code>HttpWebRequest oHttpRequestIndicesApiUrl = (HttpWebRequest)WebRequest.Create(sIndicesApiURL);
              LOG.DebugFormat("{0}:calculateIndexSecurityWeights(), Create get request to '{0}'", Name, sIndicesApiURL);
              oHttpRequestIndicesApiUrl.CookieContainer = new CookieContainer();
              foreach (Cookie oCookie in oHttpResponseIndicesParmsUrl.Cookies)
              {
                  oHttpRequestIndicesApiUrl.CookieContainer.Add(oCookie);
              }
              oHttpRequestIndicesApiUrl.AllowAutoRedirect = false;
              oHttpRequestIndicesApiUrl.Accept = ("application/json, text/plain, */*");
              oHttpRequestIndicesApiUrl.Headers.Add("accept-encoding", "gzip, deflate, br");
              oHttpRequestIndicesApiUrl.Headers.Add("accept-language", "he-IL");
              oHttpRequestIndicesApiUrl.KeepAlive = true;
              oHttpRequestIndicesApiUrl.ContentLength = 120;
              oHttpRequestIndicesApiUrl.ContentType = "application/json;charset=UTF-8";
              oHttpRequestIndicesApiUrl.Host = "api.tase.co.il";
              oHttpRequestIndicesApiUrl.Headers.Add("origin", "https://www.tase.co.il");
              oHttpRequestIndicesApiUrl.Referer = sIndicesParamsURL;
              oHttpRequestIndicesApiUrl.Headers.Add("sec-fetch-mode", "cors");
              oHttpRequestIndicesApiUrl.Headers.Add("sec-fetch-site", "same-site");

              if (oHttpResponseIndicesApiUrl.StatusCode != HttpStatusCode.OK)
              {
                  // response failed 
                  throw new ApplicationException(string.Format("get response from url '{0}' failed, Status Code: '{1}', Status Description '{2}'", sIndicesApiURL, oHttpResponseIndicesApiUrl.StatusCode, oHttpResponseIndicesApiUrl.StatusDescription));
              }
  </code></pre>
  
  <p>I can't understand why is it happening?</p>
