When a user opens the Aria Operations plugin from vCloud Director (VCD), the vCloud Director (VCD) proxy will automatically pass their session tokens in a cookie to Aria Operations.
Aria Operations then verifies the session tokens with vCloud Director (VCD)
If the session token is valid, then Aria Operations sets the current request's ID as JSESSIONID and sends it back to vCloud Director (VCD).
This valid JSESSIONID will then be used for subsequent calls.
