用URLRewriter实现URL和域名重写

http://download.microsoft.com/download/0/4/6/0463611e-a3f9-490d-a08c-877a83b797cf/MSDNURLRewriting.msi

首先下载这个安装，把URLRewriter.dll复制到web的bin目录下面。

然后在web.config里面进行如下配置

<configSections>

<section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" />

</configSections>

<RewriterConfig>

<Rules>

<!-- 产品制表者规则 -->

<RewriterRule>

<LookFor>~/Products/Beverages/.aspx</LookFor>

<SendTo>~/functions/displaypro.aspx?mid=1</SendTo>

</RewriterRule>

</Rules>

</RewriterConfig>

<httpHandlers>

<add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />

</httpHandlers>

如果是IIS6.需要对网站做以下配置

站点属性-》主目录-》配置-》添加

C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_isapi.dll

.html

取消“确认文件是否存在”前的勾

如果是II7。需对网站做以下配置

网站的处理程序映射里面的对应.aspx的映射设置访问限制，作用设置为未指定.

域名重写。

首先要把网站域名泛解析到你本机。

然后对URLRewriter的源代码里面的RewriterFactoryHandler.cs进行修改。

public class RewriterFactoryHandler : IHttpHandlerFactory

{

/// <summary>

/// GetHandler is executed by the ASP.NET pipeline after the associated HttpModules have run. The job of

/// GetHandler is to return an instance of an HttpHandler that can process the page.

/// </summary>

/// <param name="context">The HttpContext for this request.</param>

/// <param name="requestType">The HTTP data transfer method (<b>GET</b> or <b>POST</b>)</param>

/// <param name="url">The RawUrl of the requested resource.</param>

/// <param name="pathTranslated">The physical path to the requested resource.</param>

/// <returns>An instance that implements IHttpHandler; specifically, an HttpHandler instance returned

/// by the <b>PageParser</b> class, which is the same class that the default ASP.NET PageHandlerFactory delegates

/// to.</returns>

public virtual IHttpHandler GetHandler(HttpContext context, string requestType, string url, string pathTranslated)

{

// log info to the Trace object...

context.Trace.Write("RewriterFactoryHandler", "Entering RewriterFactoryHandler"); //string sendToUrl = url;url重写

string sendToUrl = context.Request.Url.AbsolutePath;//域名重写

string filePath = pathTranslated;

// get the configuration rules

RewriterRuleCollection rules = RewriterConfiguration.GetConfig().Rules; // iterate through the rules

for (int i = 0; i < rules.Count; i++)

{

// Get the pattern to look for (and resolve its URL)

string lookFor = "^" + RewriterUtils.ResolveUrl(context.Request.ApplicationPath, rules.LookFor) + "$"; // Create a regular expression object that ignores case...

Regex re = new Regex(lookFor, RegexOptions.IgnoreCase); // Check to see if we've found a match

//if (re.IsMatch(url))//URL重写

if (re.IsMatch(context.Request.Url.AbsolutePath))//域名重写

{

// do any replacement needed

//sendToUrl = RewriterUtils.ResolveUrl(context.Request.ApplicationPath, re.Replace(url, rules.SendTo));//url重写

sendToUrl = RewriterUtils.ResolveUrl(context.Request.ApplicationPath, re.Replace(context.Request.Url.AbsolutePath, rules.SendTo));//域名重写 // log info to the Trace object...

context.Trace.Write("RewriterFactoryHandler", "Found match, rewriting to " + sendToUrl); // Rewrite the path, getting the querystring-less url and the physical file path

string sendToUrlLessQString;

RewriterUtils.RewriteUrl(context, sendToUrl, out sendToUrlLessQString, out filePath); // return a compiled version of the page

context.Trace.Write("RewriterFactoryHandler", "Exiting RewriterFactoryHandler"); // log info to the Trace object...

return PageParser.GetCompiledPageInstance(sendToUrlLessQString, filePath, context);

}

}
