Session expiration refers to the automatic termination of a user’s session after a predetermined period of inactivity. Checking for session expiration is crucial for maintaining the security and integrity of web applications, as it prevents unauthorized access to sensitive data or actions.
There are several approaches to check for session expiration. One common method is to utilize a server-side script that monitors user activity and terminates the session if no activity is detected within a specified time frame. Another approach is to employ a client-side script that periodically sends a request to the server to keep the session alive.
