ASP.NET中实现二级或多级域名(URLRewriter)1.URLRewriter.DLL两个文件已经修改好,生成了复制到了Bin文件夹

ASP.NET中实现二级或多级域名(URLRewriter)
1.URLRewriter.DLL两个文件已经修改好,生成了复制到了Bin文件夹

BaseModuleRewriter.cs

C# code
protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication) sender;
            Rewrite(app.Request.Url.AbsoluteUri, app);
        }

BaseModuleRewriter.cs

C# code
protected override void Rewrite(string requestedPath, System.Web.HttpApplication app)
        {
            // log information to the Trace object.
            app.Context.Trace.Write("ModuleRewriter", "Entering ModuleRewriter");

            // get the configuration rules
            RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules;

            // iterate through each rule...
            for(int i = 0; i < rules.Count; i++)
            {
                // get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
                string lookFor = "^" + rules[i].LookFor + "$";

                // Create a regex (note that IgnoreCase is set...)
                Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);

                // See if a match is found
                if (re.IsMatch(requestedPath))
                {

                    // match found - do any replacement needed
                    string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));

                    // log rewriting information to the Trace object
                    app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);

                    // Rewrite the URL
                    RewriterUtils.RewriteUrl(app.Context, sendToUrl);
                    break;        // exit the for loop
                }
            }

2.已经做了泛解析

3.80端口主机头为空的站点

4.添加ASPNET_ISAPI的通配符应用程序映射,取消"确认文件是否存在"前的钩.

5.服务器是独立IP

规则,比如域名是abc.com
<RewriterRule>
  <LookFor>http://(\d*)\.abc\.com/</LookFor>
  <SendTo>~/2.aspx?id=$1</SendTo>
  </RewriterRule>

.aspx页面
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/2.aspx?id=2">正常URL</asp:HyperLink>
<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl="http://2.abc.com/">重写URL</asp:HyperLink>

正常访问正常URL 参数是返回参数 2
正常访问重写URL 提示 http 400错误无法找到该网页

[解决办法]
通过urlrewriter重写路径

<RewriterRule>
  <LookFor>http://(\d+)\.abc\.com/ </LookFor>
  <SendTo>/show.aspx?id=$1 </SendTo>
  </RewriterRule>

不知道LZ是怎么做的呢?不在域名服务商那里能做解释吗?，每个域名的子域名都是有限的，所以不建议用子域名来做参数使用，太浪费
