Web.config<processModel> Web.config文件是可以擴展的。你可以自定義新配置參數並編寫配置節處理程序以對它們進行處理。

web.config
<configuration>
<system.web>

</system.web>
</configuration>
XML標記。

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

示例：

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

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

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

3<compilation>
ASP.NET debug“True”.FalseWeb.config文件中有詳細說明，此處省略示例）

4<customErrors>
ASP.NET XML Web services 中發生的錯誤。

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

5<httpRuntime>
ASP.NET HTTP 運行庫設置。該節可以在計算機、站點、應用程序和子目錄級別聲明。

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

6 <pages>
<pages>可以在計算機、站點、應用程序和子目錄級別聲明。

)(

7<sessionState>
作用：為當前應用程序配置會話狀態設置（如設置是否啟用會話狀態，會話狀態保存位置）。

<sessionState mode="InProc" cookieless="true" timeout="20"/>
</sessionState>

mode="InProc"SAL
Cookie(False
表示：會話可以處於空閑狀態的分鍾數

8<trace>
ASP.NET 跟蹤服務，主要用來程序測試判斷哪裏出錯。

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

enabled="false"

(trace.axd) Web 服務器

Web.config

Web.config
1. <configSections> </configSections> .NET Framework
<configSections> 區域之後為聲明的節做實際的配置設置。

Web.config ConfigurationSettings.AppSettings Web.config

二、web.config中的session配置詳解
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

三、Asp.net 關於form認證的一般設置
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、訪問Web.config文件
ConfigurationSettings.AppSettings Web.config 文件示例：獲取上麵例子中建立的連接字符串。例如：
