Thank you so much for the video. I have a problem related to storing the session information in redis. When you opened the redis cli, i noticed that the first entry is regarding the principal, but in my case it's not present. I tried logging whether spring security is creating the user and it is, but it's not persisting the principals information along with the session id and expirations in redis. Therefore when i try to fetch the sessions linked to the user i get nothing :( NOTE: i've defined the user inside the .properties file, i don't know if that's relevant.

Do you have the necessary Redis dependency in your pom.xml?

very useful, also will be interesting to know how to manage time of storing data in redis

Thanks. Those are more advanced commands of Redis, check this link if you can find what you're looking for: redis.io/commands/expire/

You can set a timeout for the session. It will be then invalidate. Use the following configuration: server.servlet.session.timeout, docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html

Hi! I need help. We used Reddis for our Grails project and we applied changes on the Tomcat configuration. Upon testing, the session remains without relogin and also redirected to the other live pod however, session is terminated when the other replica pod goes up. Would you know why?

@TheDevWorldbySergioLema

Does the key in Redis depend on the pod? Maybe each pod creates a new key with a new hash, this makes the session unreachable for any new pod. Try to find which key is looking at Redis.

@@TheDevWorldbySergioLema Hi thanks for noticing me! No, because on the test, while logged in, the session remains even after deleting the pod. The session is remained to the other live pod. However it gets terminated when the replacement pod (from the other pod deleted) goes up. The weird thing is, the session is not related to this pod so I could not figure out why it gets terminated by the new respawn pod.

@TheDevWorldbySergioLema

In those cases, you must add more logs. Which session ID is fetching your pod, which session ID is present in Redis, which session ID is present in your browser... Logs logs logs

Excelente tu explicación Sergio. Todo muy claro sinceramente, me queda una duda y es si se puede limitar la cantidad de sesiones por usuario. Muchas gracias.

@TheDevWorldbySergioLema

Hola, si que podrías hacerlo, pero tendría que ser directamente cuando el usuario intenta hacer un signin. Tendrías que guardar la lista de sesiones activas, y actualizarlas segun vayan caducando. Para ello tendrás que create una tabla en la base de datos, Redis no podrá ayudarte tanto en este sentido

@@TheDevWorldbySergioLema Gracias Sergio, en mi caso solamente necesito implementar una sesión por usuario al hacer signin y denegar si intenta hacer otro signin, podría servirme tu ejemplo para mi caso?

Lo más sencillo sería guardar en la base de datos el estado del usuario: conectado / no-conectado. También puedes usar un contador para limitar un número de conexiones limitado (tlf, ordenador, portátil...). Para detectar si un usuario se ha deconectado, puedes vigilar constantemente la caducidad de las sesiones. El vídeo que he hecho se basa más en guardar la información de la sesión del usuario de forma que pueda compartirse con varios servidores (en caso de servicios redundantes).
