Hi
I am new to nodejs and web development and I am handling my first project.
Please, I need assistance concerning consistent sessionId because I
observed that despite my checks online and documentation that is available
online, each request generates a new sessionId in my app.
I use express-session with redis store; when, user logged in, it generate a
sessionId in redis and when I redirect the user to dashboard(after
successful login), I realise that a new sessionId is generated in express
session but not in redis. Hence, difficult to track because it is not in
redis. Further requests from dashboard, also generate a new sessionId in
express session and not in redis..
I would appreciate materials or sample codes on how to solve this challenge.
Thank you,
Femi
