    <add key="Key1" value="Val1"/>
    <add key="Key2" value="Val2"/>
</appSettings>
<connectionStrings>
    ......
    ......
</connectionStrings>
<system.web>
    <sessionState mode="InProc" timeout="20"/>
    <authorization>
        ......
    </authorization>

    <pages>
        <namespaces>
            <add namespace="System.Data"/>
            <add namespace="System.Data.SqlClient"/>
            <add namespace="System.IO"/>
        </namespaces>
    </pages>
    <customErrors mode="Off"/>
    <compilation debug="true"/></system.web>
