为了方便配置web.config文件，我写了一个常用的web.config文件的示例，可以以此为模版根据需要修改。
创建web.config文件的三种快捷方法：
1、用VS2005中的asp.net网站配置工具配置
2、参考C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727(.net framework版本)\CONFIG\目录下的machine.config 文件进行编写
3、以下边这个文件作模版修改
点击此处展开代码
<?xml version="1.0" encoding="utf-8"?>
<!--
注意: 除了手动编辑此文件以外，您还可以使用
Web 管理工具来配置应用程序的设置。可以使用 Visual Studio 中的
“网站”->“Asp.Net 配置”选项。
设置和注释的完整列表在
machine.config.comments 中，该文件通常位于
\Windows\Microsoft.Net\Framework\v2.x\Config 中
