2008年我来了...呵呵,我也跟风.
一下是ReUrlModule.HttpModule的所有类.

一下是前台基类的PageBase:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
namespace ReUrlModule.WebApp
{
public class PageBase:ReUrlModule.HttpModule.FormAction
{
}
}
以下是网站的web.config文件的配置:
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<pages pageBaseType ="ReUrlModule.HttpModule.FormAction,ReUrlModule.HttpModule" />
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true" />
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows" />
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
<httpModules>
<add name="RewriteURL" type="ReUrlModule.HttpModule.URLmodule,ReUrlModule.HttpModule" />
</httpModules>
</system.web>
</configuration>
以上的代码没有注释,但是也不需要都是从网上收罗的.也就是不是自己的东东.只是自己总结了一下,上面的代码没有写全.
还需要处理Ｃｓｓ,图片的地址问题,不过假如是用二级站点架构或者是使用CDN网络的话基本上就不需要了.
好像还有个SSO的类库.我不知道放那里了,找到了就发出来吧
趁现在还有心情写点东西呵呵.
