我使用HttpWebRequest的方式是你的意思:当我完成它时,处理响应,希望这会使它重用任何可用的TCP连接,但是不会:收到响应后关闭连接。我在使用TCPView时看到了这种情况。
这是我的HttpWebRequest代码:
private HttpWebResponse ExecuteRequest(String baseRelativeUri, String method, Ds postValues) {
/////////////////////////////////////////
// Set-up
Uri uri = new Uri( _baseUri, baseRelativeUri );
_cookies.ProcessDomains();
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create( uri );
request.CookieContainer = _cookies;
request.Method = method;
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0";
if( postValues != null ) SetPostContent( request, postValues );
/////////////////////////////////////////
// Response
return (HttpWebResponse)request.GetResponse();
}
protected HtmlDocument ExecuteRequestHtml(String baseRelativeUri, String method, Ds postValues, HttpStatusCode expectedStatusCode) {
using(HttpWebResponse response = ExecuteRequest(baseRelativeUri, method, postValues)) {
if( response.StatusCode != expectedStatusCode ) throw new WebException("Did not receive " + expectedStatusCode + " response.");
/////////////////////////////////////////
// HtmlDocument
using(Stream stream = response.GetResponseStream()) {
HtmlDocument doc = new HtmlDocument();
doc.Load( stream );
return doc;
}
}
}
根据MSDN,HttpWebRequest.KeepAlive属性默认为true,HttpWebRequest.Pipelines也是如此。那么我做错了什么?
谢谢!
答案 0 :(得分:2)
事实证明我正在达到HttpWebRequest所尊重的“每个主机的2个同时连接”规则。
解决方案是设置此静态属性:
System.Net.ServicePointManager.DefaultConnectionLimit = 15;
