impact for just not knowing what to do with flow.
I'm having difficulties following you - a plain 303 redirect to a "Thank
you" page shouldn't cause all of that. It's an HTTP reply with the 303
and the new URL, followed by a single URL request from the browser.
OK. I think I know how other people (like you) think about just
requesting URL's one after another. If that's not such a performance
issue for you, fine.
A plain 303 redirect mostly isn't just a HTML file, it's another script
(or the same script with another action falling through a switch
statement, whatever).
Point is: why hitting you webserver with multiple requests per user,
just after submitting a form or whatever caused the redirect? If you
have 2 users per day, that won't hurt. But if you have 30.000 concurrent
users a minute, that could be 60.000 requests (besides all the images,
stylesheets, javascripts that are being re-requested). Or am I talking
nonsense?
