You can use public properties on the code behind as well as the session. Here is a sample using public properties that can be read from a Javascript function.

Front End:

function IsAgentInProgram()
{
    var optStatus = "<%=AgentOptInStatus%>";

    if (optStatus == "True")
        alert("You are opted in!");
    else
        alert ("You are opted OUT");
}

Code Behind:

public bool AgentOptInStatus;

private void Page_Load(object sender, System.EventArgs e)
{
    this.AgentOptInStatus = true;

}
