Re: (Dis)Proving that 303s have a performance impact.

btw. i guess it's totally clear to all here, that a redirect requires
another another GET, nobody will doubt that. the debate is about putting
such notices that scare off people (who don't known anything about
redirects and stuff) into the spec. people get the feeling, that they
can do something really wrong ("oh dear, performance, i can slow down
the whole internet...")

putting something along the line "when choosing your personal WebID be
adviced by ${linkToCoolURIs}" would be a good compromise plus people
would (maybe) read the cooluris doc, which is for everybody's benefit.
plus it is along the lines with another link (the one to some best
practice guide) in the spec.

A client looking up a set of terms through 303 may use many requests, even though the first request has already loaded everything there is to know.
