I've found a bit of discrepancy with regards to the case of the
"server" portion, so the above code just normalizes it to
lowercase and then shoves it in a dictionary.
You can then do as you please with the contents of the "server"
variable.
It's theoretically possible that the server can return differing
headers based on the URL you request or its method. You'll have
to adjust the request() call for the method (GET/HEAD/POST, etc)
and for the resource you want (in this case, just "/")
