Squid will request authentication for each fetch.

The first time you try to fetch something through the proxy, an error will
be returned saying 'proxy authentication required' to your browser.

Your browser then prompts you for your username and password. It then
caches that information in memory (unless you tick the box 'Remember my
username and password').

Whenever it submits a request for an object, it includes the username and
password information with the request automatically.

So - your browser is not maintaining a persistent connection but
remembering the username and password you gave it. This is being sent to
the proxy automatically by your brwoser, without you having to type it in
again.

Hope this explains things,
