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");
        }
    }
}
