[lug] Off topic: java form-based authentication in a client program

[bgiles at coyotesong.com]

Nope -- form-based authentication passes the username & password to the
j_security_check action.  That action sets a JSESSIONID cookie that's used
to identify the client in subsequent visits.

Okay, I lie.  There's also a mode where all of the URLs are rewritten to
include a JSESSIONID=XXXXXXXXXXXX, but it's undoubtably easier to deal
with cookies programmatically.
