Is it possible something like this?
Kahlil didn't say each user needed their own cache, he was describing a reason why a cache that doesn't clone the form object would fail. As long as the cache gives a clone of the original form each time it's requested, there should be no problem. > I just found that I need to put a login form on all the pages, so the speed > of the entire site would decrease very much because of this... A form framework has benefits, but it doesn't have to be used 100% of the time. If the login form on all pages is static (just username / password fields), you could probably hardcode the form html in your template file.
