利用UrlRewriter实现重写url

利用Open Source Intelligencia.UrlRewriter实现重写url
      实现效果如下：
　　~/video 到 ~/*.aspx(或者~/tags/*.aspx)
     ~/a.htm(或者自定义的扩展名) 到 ~/a.aspx
     ~/class/(.+)   到  ~/Class/Default.aspx?classid=$1
     等效果

    方法如下：
　　（１）下载Intelligencia.UrlRewriter.dll文件
　　（２）将Intelligencia.UrlRewriter.dll引用到你的website程序中
　　（３）配置webconfig
　　　　 １）添加　Configuration section handler:
<configSections>
  <section
   name="rewriter"
   requirePermission="false"
   type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter" />
 </configSections>

　　　　 ２）添加 UrlRewriter mapper HttpModule:
<system.web>
  <httpModules>
   <add
    type="Intelligencia.UrlRewriter.RewriterHttpModule, Intelligencia.UrlRewriter"
    name="UrlRewriter" />
  </httpModules>
 </system.web>
　　　　３）添加 重写规则到 web.config的configuration结点中，如下
<rewriter>
<rewrite url="/tags/(.+)" to="/tagcloud.aspx?tag=$1" /> 
 </rewriter>
整个web.config文件

 1 <? xml version="1.0" ?>
 2 < configuration >
 3      < configSections >
 4          < section
 5              name ="rewriter"
 6             requirePermission ="false"
 7             type ="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter"   />
 8      </ configSections >
 9      < appSettings />
10      < connectionStrings />
11      < system.web >
12          < httpModules >
13              < add
14                  type ="Intelligencia.UrlRewriter.RewriterHttpModule, Intelligencia.UrlRewriter"
15                 name ="UrlRewriter"   />
16          </ httpModules >
17
18     
19          < compilation  debug ="true" />
20         
21          < authentication  mode ="Windows" />
22
23      </ system.web >
24     
25      < rewriter >         
26          < rewrite  url ="~/tags/(.+)"  to ="~/tag/tagcloud.aspx?tag=$1"   />
27          < rewrite  url ="~/video"  to ="~/Class/Default.aspx"   />
28          < rewrite  url ="~/class/(.+)"  to ="~/Class/Default.aspx?classid=$1"   />
29
30          < rewrite  url ="~/test_([a-zA-Z]+).aspx$"  to ="~/Show.aspx?Code=$1"  processing ="stop"   />
31          < rewrite  url ="~/test_([a-zA-Z]+).html$"  to ="~/Show.aspx?Code=$1"  processing ="stop"   />
32      </ rewriter >
33     
34 </ configuration >
35

　　（４）如果需要重写为htm、其它扩展名或者没有扩展名的url时，需要在IIS中设置
　　　设置方法如下：
        在windowXP系统中：
           　 １）Open Up IIS and Navigate to the “Home Directory Tab” 
               ２）Select “Configuration” 
               ３）Click “Add” and enter “C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_isapi.dll” in the Executable box. For the file extension, enter “.*”. Finally, make sure that “Check that file exists” is not checked. 
        在window 2003server中请参考：
