Only if excplicitly told to, and then without validating the

Responses to requests with authentication is cached if either

a) The server sends "Cache-Control: public" telling caches that the
content is public and do not really require authentication.

b) The ignore-auth is used in squid.conf http(s)_port or refresh_pattern
directives to acheive the same effect as described above.

That's not normal unless you are playing with the Reload button.

Note: In reverse proxies you can use the ignore-cc flag telling Squid to
ignore Cache-Control sent by clients. The reverse proxy is an extension
of your web server.
