An IBM Worklight error occurs in authentication after the session has expired

Resolving The Problem

To resolve this issue, change the client application code to re-initiate the login procedure on the new session, by using the following code in the challenge handler:
j
sampleAppRealmChallengeHandler.isCustomResponse = function(response) {
    if (!response || response.responseText === null) {
        return false;
    }
    var indicatorIdx = response.responseText.search('j_security_check');

    if (indicatorIdx >= 0 && response.status != 404){
        return true;
    }  
    return false;
};

Because of the additional condition in boldface type, the client re-requests the original protected resource, which re-initializes the server authentication state. This re-initialization causes the server to resend the form to the client application. As a result, a second attempt to submit the login to "j_security_check" should now be successful.

For more information, see the product documentation. In particular, see the "Form-based authentication" Getting Started module that you can find in the "Tutorials and samples" topic, under category 8. Authentication and security.
