自己正在用的url转义控件(带源码)

忘记最初的源码怎么来的了，好像是微软的吧，后来觉得那个配置实在太烦琐了，用起来很是不方便。
略微改了一下，初来报道，大家给个意见

使用方法：
1.
web.config
添加：
<?xml version="1.0"?>
<configuration>
    <system.web>
        <httpModules>
            <add name="ModuleRewriter" type="JIAOLG.URLRewriter.ModuleRewriter, UrlRewriter"/>
        </httpModules>
    </system.web>
</configuration>

2.
把UrlRewriter.dll复制到bin目录

3.
把rewriter.xml复制到App_Data

部分源码：

using  System;
using  System.Web;
using  System.Web.Caching;
using  System.Xml;
using  System.Text.RegularExpressions;

namespace  JIAOLG.URLRewriter
{
     public   class  ModuleRewriter : BaseModuleRewriter
    {
         private   static   readonly   string  cname  =   " rules " ;
         private  XmlNodeList rules;

         protected   override   void  Rewrite( string  requestedPath, System.Web.HttpApplication app)
        {
            app.Context.Trace.Write( " ModuleRewriter " ,  " Entering ModuleRewriter " );

             if  (HttpRuntime.Cache[cname]  ==   null )
            {
                CacheDependency cd  =   new  CacheDependency(Rules.ConfigFile);
                
                rules  =   new  Rules().getRules();
                HttpRuntime.Cache.Insert(cname, rules, cd);
            }
             else
            {
                rules  =  (XmlNodeList)HttpRuntime.Cache[cname];
            }

             //  iterate through each rule
             foreach  (XmlNode rule  in  rules)
            {
                 string  lf  =  rule.FirstChild.SelectSingleNode( " lookfor " ).InnerText;
                 string  st  =  rule.FirstChild.SelectSingleNode( " sendto " ).InnerText;
                 string  lookFor  =   " ^ "   +  RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, lf)  +   " $ " ;

                Regex re  =   new  Regex(lookFor, RegexOptions.IgnoreCase);

                 if  (re.IsMatch(requestedPath))
                {
                     string  sendToUrl  =  RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, st));

                    app.Context.Trace.Write( " ModuleRewriter " ,  " Rewriting URL to  "   +  sendToUrl);

                    RewriterUtils.RewriteUrl(app.Context, sendToUrl);
                     break ;
                }
            }

            app.Context.Trace.Write( " ModuleRewriter " ,  " Exiting ModuleRewriter " );
        }
    }
}
