Multiple browser instances

Control Center relies on HTTP sessions to maintain state information between requests while a user is logged in. It relies on a session identification cookie that is transmitted by the web browser with each request. The browser stores the cookie value and controls whether the same cookie value is shared between instances of the browser. Most web browsers that support multiple tabs, including Firefox and Internet Explorer, share the value between the various tabs. Many browsers also share the value between separate browser windows.

When you access the Control Center from multiple browser instances on the same client computer, be aware that unexpected results can occur unless unique session identifiers are presented in the request from the client. Issues primarily happen when two instances from the same computer access the same pages or access the same type of data that is displayed on different pages. To prevent errors, ensure that a unique session is in use in a new browser instance. To ensure that a unique session is used, do the following steps:
  1. Refresh the page that is being viewed in the current instance before you open a new one to ensure that the session is active and did not time out.
  2. Open the new instance.
  3. Access the Control Center.
  4. If a login page is presented, a new session is in use.
