protected void Button1_Click(object sender, EventArgs e)
{
string url = "http://" + Request.Url.Authority + "/default.aspx";
new System.Net.WebClient().DownloadFile(url, Server.MapPath("~/default.html"));
Response.Redirect("default.html");
}

这个代码方案也是参考了很多人的代码写出的。在此对这些无名的奉献者表示感谢。
贴一个核心的代码吧：
using System;
using System.Web;
using System.Web.UI;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
using System.Configuration;
namespace BLL
{
/// <summary>
/// PageBase 的摘要说明。
/// </summary>
public class PageBase : Page
{
private static object obj = new object();
//// <summary>
/// 重写默认的HtmlTextWriter方法，修改form标记中的value属性，使其值为重写的URL而不是真实URL。
/// </summary>
/// <param name="writer"></param>
protected override void Render(HtmlTextWriter writer)
{
string url = Request.RawUrl.ToLower();
if (Request.RequestType.ToLower().Equals("get"))
{
URLRewrite u = (URLRewrite)HttpContext.Current.Items["siteurl"];
if (u != null && u.Cache > 0)
{
string CacheFile = Server.MapPath("/Cache" + url + ".html");
FileUtil.CreateDirectory(CacheFile);
lock (obj)
{
using (StreamWriter sw = new StreamWriter(CacheFile, false, Encoding.UTF8))
{
base.Render(new FetchHtmlWriter(writer, sw));
sw.Flush();
sw.Close();
sw.Dispose();
}
Cache.Add(url, string.Empty, null, DateTime.Now.AddSeconds(u.Cache), TimeSpan.Zero, System.Web.Caching.CacheItemPriority.High, null);
return;
}
}
}
if (writer is System.Web.UI.Html32TextWriter)
{
writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
}
else
{
writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
}
base.Render(writer);
}
}
public class FormFixerHtml32TextWriter : System.Web.UI.Html32TextWriter
{
public FormFixerHtml32TextWriter(TextWriter writer)
: base(writer)
{
}
public override void WriteAttribute(string name, string value, bool encode)
{
// 如果当前输出的属性为form标记的action属性，则将其值替换为重写后的虚假URL
if (string.Compare(name, "action", true) == 0)
{
value = HttpContext.Current.Request.RawUrl;
}
base.WriteAttribute(name, value, encode);
}
}
public class FormFixerHtmlTextWriter : System.Web.UI.HtmlTextWriter
{
public FormFixerHtmlTextWriter(TextWriter writer)
: base(writer)
{
}
public override void WriteAttribute(string name, string value, bool encode)
{
if (string.Compare(name, "action", true) == 0)
{
value = HttpContext.Current.Request.RawUrl;
}
base.WriteAttribute(name, value, encode);
}
}
}

有不清楚的地方，可以加QQ群：49745612一起探讨。
跟前一种，生成静态页面的方案比，这种复杂得多，个人更喜欢前面的实现方式。
