The precise answer depends on your servlet engine (some allow you to configure
the details of session cookies), but all of the ones I am familiar with use the
default "maximum age" setting of the javax.servlet.http.Cookie class, which tells
the browser to keep this cookie until it exits. As a side effect (for Netscape,
at least) this causes the cookie to never be written to the "cookies.txt" file,
because there will never be a reason to keep it past the current invocation of
the browser.
