解决方案

您是否尝试过的<一个HREF =htt​​p://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.keepalive.aspx> HttpWebRequest.KeepAlive 的财产？它设置适当的保持活动的HTTP标头不持续的连接。 （当然，这也必须得到支持并通过远程Web服务器启用）。

的

的 HttpWebRequest.KeepAlive 在MSDN文档指出它是默认的HTTP1.1连接设置为真正，所以我怀疑你试图联系不允许连接持久服务器。

代理会自动使用和设置从您的系统采取（读Internet Explorer）中的设置。它也可以覆盖通过 HttpWebRequest.Proxy 物业代理服务器设置或者通过调整应用程序配置文件（请参见 http://msdn.microsoft.com/en-us/library /kd3cf2ex.aspx ）。

How do i keep a connection alive in C#? I'm not doing it right. Am i suppose to create an HttpWebRequest obj and use it to go to any URLs i need? i dont see a way to visit a url other then the HttpWebRequest.Create static method.

How do i create a connection, keep it alive, browse multiple pages/media on the page and support proxys? (i hear proxy are easy and support is almost standard?) -edit- good answers. How do i request a 2nd url?

{
HttpWebRequest WebRequestObject = (HttpWebRequest)HttpWebRequest.Create("http://google.com");
WebRequestObject.KeepAlive = true;
//do stuff
WebRequestObject.Something("http://www.google.com/intl/en_ALL/images/logo.gif");
}

解决方案

Have you tried the HttpWebRequest.KeepAlive property? It sets the appropriate Keep-Alive HTTP header and does persist the connections. (Of course this must also be supported and enabled by the remote web server).

The HttpWebRequest.KeepAlive documentation on MSDN states that it is set to true by default for HTTP1.1 connections, so I suspect the server you're trying to contact does not allow connection persistence.

Proxy is used automatically and its settings are taken from your system (read Internet Explorer) settings. It is also possible to override the proxy settings via HttpWebRequest.Proxy property or by tweaking the application configuration file (see http://msdn.microsoft.com/en-us/library/kd3cf2ex.aspx).
