I am developing a website using PHP and I want to store data on my user/browser's cache so I can keep the data through PHP pages without moving it all the time through GET or POST. I have used APC and APCu functions to make this work (Because I need the key-value system).
However, I think I'm using the system cache (?) instead of the user's cache so when I try to run my program at multiple computers the cache of these users adds up. I would like this to be individual for each computer/user. I cannot find almost any APC/APCu functions whose parameters include the cache type of 'user' instead of 'system' (default) -- (like in apc_clear_cache('user') for example)
Am I not using the right caching mechanism (APC, APCu, OPCache), am I missing parameters, or is it something else?
