自己写的用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：









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");
}
}
}
