Laravel cache doubt

I've worked with php a few years ago and used Code Igniter, in it I remember there was a problem. When two people log on to the site and their computers were on the same network the system would eventually return each other's data. This was possible to solve, but in Laravel I did not find anything on. What I find is about using the cache but not on that subject. Could someone tell me somewhere to talk about it? I did not find anything specific in the documentation.
