博客给出了使用亿牛云爬虫代理时要访问的目标页面示例，目标页面为http://httpbin.org/ip ，体现了爬虫代理在信息技术领域的应用。

// 要访问的目标页面
string targetUrl = “http://httpbin.org/ip”;

// 代理服务器
string proxyHost = "http://t.16yun.cn";
string proxyPort = "6447";

// 代理隧道验证信息
string proxyUser = "16IXNGXO";
string proxyPass = "366338";

// 设置代理服务器
WebProxy proxy = new WebProxy(string.Format("{0}:{1}", proxyHost, proxyPort), true);


ServicePointManager.Expect100Continue = false;

var request = WebRequest.Create(targetUrl) as HttpWebRequest;

request.AllowAutoRedirect = true;
request.KeepAlive = true;
request.Method    = "GET";
request.Proxy     = proxy;

//request.Proxy.Credentials = CredentialCache.DefaultCredentials;

request.Proxy.Credentials = new System.Net.NetworkCredential(proxyUser, proxyPass);

// 设置Proxy Tunnel
// Random ran=new Random();
// int tunnel =ran.Next(1,10000);
// request.Headers.Add("Proxy-Tunnel", String.valueOf(tunnel));


//request.Timeout = 20000;
//request.ServicePoint.ConnectionLimit = 512;
//request.UserAgent = "Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.82 Safari/537.36";
//request.Headers.Add("Cache-Control", "max-age=0");
//request.Headers.Add("DNT", "1");


//String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(proxyUser + ":" + proxyPass));
//request.Headers.Add("Proxy-Authorization", "Basic " + encoded);

using (var response = request.GetResponse() as HttpWebResponse)
using (var sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
    string htmlStr = sr.ReadToEnd();
}
