I dont know the exact wording for the answer i am seeking or if this is the correct place it ask, so bare with me please.
----------
When we from over OS initiate a network session with a service like google.com, the OS generate a numeric value
that (from what i know) it links to the (GUI) window and the session we create so the information we request from google.com
goes to the correct window that initiated the session.
My question:
#1 How is this numeric value written in the header? Is their a specific field for this?
#2 Anyone know what RFC the above would be under?
The numeric value is not really an open port number that the OS creates a open socket for and listens on.
It's a very open question so please dont hesitate if i need to elaborate on what i mean.
Thanks on advance
Kind regards!
