6.<sessionState>

Web.config<processModel> Web.config文件是可以扩展的。你可以自定义新配置参数并编写配置节处理程序以对它们进行处理。

web.config
<configuration>
<system.web>

</system.web>
</configuration>
XML标记。

1<authentication>
ASP.NET WindowsFormsPassPortNone< authentication> <authorization> 节配合使用。

示例：

Forms
<authentication mode="Forms" >
<forms loginUrl="logon.aspx" name=".FormsAuthCookie"/>
</authentication>
loginUrlnameCookie名称。

2<authorization>
URL <authentication> 节配合使用。


<authorization>
   <deny users="?"/>
</authorization>
user.identity.nameweb.Security.FormsAuthentication.RedirectFromLoginPage.具体的

3<compilation>
ASP.NET debug“True”.FalseWeb.config文件中有详细说明，此处省略示例）

4<customErrors>
ASP.NET XML Web services 中发生的错误。


<customErrors defaultRedirect="ErrorPage.aspx" mode="RemoteOnly">
</customErrors>
defaultRedirectmode Web ()信息。

5<httpRuntime>
ASP.NET HTTP 运行库设置。该节可以在计算机、站点、应用程序和子目录级别声明。

4M60100
<httpRuntime maxRequestLength="4096" executionTimeout="60" appRequestQueueLimit="100"/>

6 <pages>
<pages>可以在计算机、站点、应用程序和子目录级别声明。

)(

7<sessionState>
作用：为当前应用程序配置会话状态设置（如设置是否启用会话状态，会话状态保存位置）。


<sessionState mode="InProc" cookieless="true" timeout="20"/>
</sessionState>
mode="InProc"SAL
Cookie(False
表示：会话可以处于空闲状态的分钟数

8<trace>
ASP.NET 跟踪服务，主要用来程序测试判断哪里出错。

Web.config
<trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true" />
enabled="false"



 (trace.axd) Web 服务器

Web.config

Web.config
1. <configSections> </configSections> .NET Framework
<configSections> 区域之后为声明的节做实际的配置设置。


<configuration>
 <configSections>
 <section name="appSettings" type="System.Configuration.NameValueFileSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
</configSections>
 <appSettings>
 <add key="scon" value="server=a;database=northwind;uid=sa;pwd=123"/>
 </appSettings>
 <system.web>
 ......
 </system.web>
</configuration>

二、web.config中的session配置详解
Web.config
< sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>
SessionsessionState
< sessionState mode="Off|InProc|StateServer|SQLServer"
             cookieless="true|false"
             timeout="number of minutes"
             stateConnectionString="tcpip=server:port"
             sqlConnectionString="sql connection string"
             stateNetworkTimeout="number of seconds"
/>

 If (Session("MySession")Is Nothing) Then
 span1.InnerHtml = "NOTHING, SESSION DATA LOST!"

三、Asp.net 关于form认证的一般设置
asp.net form
web.configform
   <authentication mode="Forms">
            <forms name="auth" loginUrl="index.aspx" timeout="30"></forms>
</authentication>
<authorization>
        <deny users="?" />
</authorization>
2: ;
<configuration><system.web>,<system.web>..</system.web>;
---------------- userReg.aspx.
<location path="userReg.aspx">
  <system.web>
     <authorization>
         <allow users="?" />
     </authorization>
  </system.web>
</location>
3 , ;
if()

System.Web.Security.FormsAuthentication.SetAuthCookie(, false);


四、访问Web.config文件
ConfigurationSettings.AppSettings Web.config 文件示例：获取上面例子中建立的连接字符串。例如：
