getVariable	String	String name	Retrieve the currently stored value of the named variable.
setVariable	void	String name, String value	Store a new value for the named variable.

Example

An example of a session variable – during sign-on, we are redirected to the login page of the target application. We want to store this because we base the logout URL on the login URL.

this.onGetLoginResponse = function(ctx) {
 
    var loginPage = ctx.appResponse.getHeader('location');
 
    // (various error checks here)
 
 
    ctx.appSession.setVariable("loginPage", loginPage);
 
 
    // (continue login sequence)
}
 
 
this.signOff = function(ctx) {
 
    ctx.startSsoRequest("GET", ctx.appSession.getVariable("loginPage").replace("login", "logout"),
        function onLogoutResponseWrapper(ctx) { self.onLogoutResponse(ctx); });
};
