That's simply not how HTTP works.  When a browser makes a request, the
server sends back a page of HTML, typically within less then a second,
and then the connection is terminated.  The browser will eventually
display what it received, and fetch other resources like stylesheets and
images, but those are all totally separate requests.

It is a common mistake among beginners to think that the connection to
the server is maintained as long as the page is displayed (I know my
wife believes that), but it's not true.  There's a quick connect,
transfer, and disconnect, then the rest happens in the browser without a
connection.

So, it doesn't make any sense to allow one connection at a time.  I
suppose you could have the concept of an "active login" where no one
else could log in while the first user was there, but you'd have to
implement that yourself, by remembering the currently logged in user in
some common location.  But remember, there is no guarantee that you're
going to get a logout request.  If the user logs in, and then switches
to Google, your site would be locked out.
