好吧，
网址解决是这样的：
http://some.domain.com/?w=/@attach&f...=Brusselse.wmv
HttpWebRequest请求;
request =（HttpWebRequest）HttpWebRequest.Create（url）;
request.AllowAutoRedirect = false;
request.Method =" GET";
CredentialCache wrCache = new CredentialCache（）;
wrCache.Add（new Uri（url），" Basic"，new NetworkCredential（username，password））;
request.Credenti als = wrCache;
HttpWebResponse response =（HttpWebResponse）request.GetResponse（）;
string newurl = GetRedirectURL（response）; //它通过一个
重定向，这个函数获取新的URL
比我再次做请求/响应使用新网址，并最终下载HTML
域中某个未知页面的页面源代码。 （也许是登录页面。）

Well,
The URL to resolve is something like this:
http://some.domain.com/?w=/@attach&f...=Brusselse.wmv
HttpWebRequest request;
request = (HttpWebRequest)HttpWebRequest.Create(url);
request.AllowAutoRedirect=false;
request.Method = "GET";
CredentialCache wrCache = new CredentialCache();
wrCache.Add(new Uri(url),"Basic",new NetworkCredential(username,password));
request.Credentials = wrCache;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string newurl = GetRedirectURL(response); // it goes trough one
redirection, this function gets the new URL
Than I again do "request/response" with new url, and end up downloading HTML
page source code of some unknown page in the domain. (Maybe the logon page).

嗯，
要解决的URL是这样的：
http://some.domain.com/?w=/@attach&f...= Brusselse.wmv
HttpWebRequest请求;
request =（HttpWebRequest）HttpWebRequest.Create（url）;
request.AllowAutoRedirect =假;
出于好奇：为什么需要实施自己的重定向处理？
request.Method =" GET";
CredentialCache wrCache = new CredentialCache（）;
wrCache.Add（new Uri（url），" Basic"，new
NetworkCredential（username，password））;
request.Credentials = wrCache;
HttpWebResponse response =（HttpWebResponse）request.GetResponse（）;
string newurl = GetRedirectURL（response）; //它通过一个
重定向，这个函数获取新的URL

Out of curiosity: Why do need to implement your own redirection handling?
request.Method = "GET";
CredentialCache wrCache = new CredentialCache();
wrCache.Add(new Uri(url),"Basic",new
NetworkCredential(username,password));
request.Credentials = wrCache;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string newurl = GetRedirectURL(response); // it goes trough one
redirection, this function gets the new URL
但是到目前为止究竟发生了什么？你确定你没有丢失你的
凭证或会话cookie吗？

But what exactly happens at this point? Are you sure you''re not losing your
credentials or a session cookie?
