Issue/Introduction

How and where can we allocate memory for the WebApp user sessions? 

What's the best method to determine how much memory each user session is using?

By default each WebApp Session is capped at a maximum of 1024MB (1GB).  (This is not a hard cap and in some instances, the process can go over, due to Garbage Collection, JIT Optimization, Off-heap allocations, etc)

You can view or modify the setting as follows:
