Rick,
you are mixing something.
$_session array is stored on the server while sessionstorage is stored on the
clients computer.
I am not sure that there is a direct way to let Livecode Server read
sessionstorage directly from the clients computer, but i might be wrong.
At least PHP is not able.
One way would be to use Javascript to read the storagesession and post it to a
LC Server script using Ajax.
You could even do this from one single LC server script.
In the script you would check if the $_POST array contains any data.
If the $_POST array is empty, then you have to execute the javascript that
fetches the sessionstorage data and if there is sessionstorage then it posts
that data to the script again.
If the $_POST array is not empty, then you can continue the script using the
sessionstorage data.
At least this is the way how it is done in .php
I've used this method a lot for processing form data.
