We have a website WordPress website running on AWS and it has ELB implemented on it. I have to save UTM data of each visitor whenever it reaches to our website and has to keep it for the whole session of a particular user.
I used $_SESSION for the same purpose it's in vain as we know AWS does not support $_SESSION on ELB. We searched for the alternative and found it that it can be possible by using Sticky Sessions on AWS.
Now, the problem is that we have no idea how we can implement Sticky Sessions. Can you please let us know how we can use Sticky Sessions on AWS?
