此博客展示了一段ASP.NET代码，定义了RequestGet方法用于发送HTTP GET请求获取页面内容。代码中设置了请求的各种属性，如协议版本、请求方法、超时时间等，还处理了自动重定向和异常情况，最终返回页面内容或错误信息。

private string RequestGet(string TheURL, string TheProxy)
  {
   Uri uri = new Uri(TheURL);
   HttpWebRequest request = (HttpWebRequest) WebRequest.Create(uri);
   string page;
   try
   {

request.KeepAlive = false;
request.ProtocolVersion=HttpVersion.Version10;

request.Method = "GET";

request.ContentType = "application/x-www-form-urlencoded";

request.Proxy = System.Net.WebProxy.GetDefaultProxy();

//allow auto redirects from redirect headers
request.AllowAutoRedirect=true;

//maximum of 10 auto redirects
request.MaximumAutomaticRedirections=10;

//30 second timeout for request
request.Timeout=(int) new TimeSpan(0,0,60).TotalMilliseconds;

    //give the crawler a name.
    request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
    //request.UserAgent="Mozilla/3.0 (compatible; My Browser/1.0)";

    HttpWebResponse response = (HttpWebResponse) request.GetResponse();
    Stream responseStream = response.GetResponseStream();
    StreamReader readStream = new StreamReader (responseStream, System.Text.Encoding.Default);

    page = readStream.ReadToEnd();
   }
   catch (Exception ee)
   {
    page = "Fail message : "+ee.Message;
   }
   return page;

}
