这可能对您有所帮助.试试

May this helps you. try it

 HttpWebRequest request = HttpWebRequest. CreateHttp (s);
    request.Headers[HttpRequestHeader.CacheControl] = "no-cache"; 
    request.Headers[HttpRequestHeader.Pragma] = "no-cache"; 
    request.Headers[HttpRequestHeader.IfModifiedSince] = dateTime.Now.ToString();
    request. BeginGetResponse (new AsyncCallback (HandleResponse), request);

/*request.Headers[HttpRequestHeader.IfModifiedSince] = dateTime.Now.ToString(); this forces your request to always be performed - this made the trick for me.*/
