    How can i access a web.config key in javascript. There is complex javascript function already written in a .js file and I need to add a value associated with the key - AUTHENTICATION_FLAG in a javascript function. I am coding this in C#.  --- > ConfigurationManager.AppSettings["AUTHENTICATION_FLAG"]

    Thank you in advance

    You need to read it in the codeBehind to a protected variable like


    protected string strAppTitle = ConfigurationSettings.AppSettings["AppTitle"];

    Then in the JavaScript, you can use

    var strAppTitle = "<%=strAppTitle%>" ;

    This worked really as expected. But what is logic or how it manages?

    How is the protected variable accessible on client side?

    <script type="text/javascript">
        function ReadConfigurationSettings()
            var k = '<%=ConfigurationManager.AppSettings["var1"].ToString() %>'
