windows-phone-7 - Windows Phone 7 中的 Httpwebrequest 缓存

Question

我在使用 wp7 开发应用程序时遇到缓存问题。 1 和 httpwebrequest 方法。

HttpWebRequest request = HttpWebRequest. CreateHttp (s);
request. BeginGetResponse (new AsyncCallback (HandleResponse), request);

即使请求内容不同，请求的结果也是一样的。并且在请求中的参数不同的情况下。我该如何解决这个问题？

谢谢。

Answer 1

希望这对你有帮助。试试吧

 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.*/
