I recently had cause to revisit viewing/editing the values in the volatile environment key, within the view desktop session, for a customer who needed to identify various pieces of information from the connecting endpoint. One of our Devs needed to be able to find this information and pass it through to Systrack to create some bespoke dashboards, using what is produced within the volatile environment key. There’s some really useful information in here if you’ve never had cause to go through it!
