    Dear Team, 

    We have an asp.net core application configured with azure b2c. 

    The problem what we are facing is when we keep the application idle for more than one hour and try to post the data using jquery ajax call we are getting an un authorized error. 

    How to handle this scenario. Please advice..

    the asp.net core app should return a not authorized error to the ajax call, and the client code should login in again.

    var dataPromise = fetch(url, {
      method: 'POST', 
      body: JSON.stringify(data),
        'Content-Type': 'application/json'
    }).then(function(response) {
        if (response.status >= 200 && response.status < 300) {
           return (/^application\/json/.test(response.headers.get("content-type")))
             ? response.json();
             : response.text();
        } else if (response.status == UnauthorizedStatus) {
            // handle login
        } else
            // handle standard error

    if their login expires, they need to login again, its the only way to get a token. you could use a long lasting renewal token, that the server stores (not in session), and renew the ticket via the renewal token.

    Hi Selvakumar,

    For default lifetime for token is 60 minutes, after idle for more than one hour, the token will be invalid for the next time, I suggest you try to increase the lifetime by following link below:

    Best Regards,
