You don't have to authenthicate on every page without cookies. HTTP:Basic authenthication is
implemented in such a way in browsers that they ask only once for username and password for a
site, aslong as subsequent pages use the same Authenthication-realm, the same username and
password is authomatically reused.
Yes, technically this means your BROWSER authenthicates every request, but you the USER don't
see this and aren't inconvenienced by it.
You do need to reauthenthicate if you close and reopen your browser though, cookies can
prevent that, if desired.
