Hello Alan,
Could you give me a bit more information please?

On my webpage, when I press start, the following is run:
def start_server(name, port):
    connection = Connection(name, port)

So when I close this page, I loose "connection". How could I put this in a 
dictionary or cookie for later reference?

I'm not sure I understand your issue?
What part of 'put this in a dictionary' do you not understand?

mydict[(port,name)] = connection

would be one way...

And when you say on your web page the following is run... 
Do you mean the function is executed on the browser? Or do you mean you 
submit some information to the server which executes the code?
If so that begs the question which web framework you are using?

Somehow you need to create a mechanism for retrieving the connection.
That retrieval must be based on some kind of name/key that can be stored 
or recreated by the web client. A dictionary is only one possibility.
