Edit Question
Title
Body
I need a simple user identification system for the purpose of allowing/prohibiting an action . This is not a high-security requirement and it is ok to make mistakes (eg same user will execute non-allowed action using different browsers). To be less abstract, let's see at the StackOverflow voting and assume we want to allow voting by public audience , but only once. The simplest thing that can work - is using a cookie : set a new cookie per answer; store all votes in one cookie (or combine these somehow). This is a bit unreliable due to the limitations of a cookie size/number . It will also sent the cookie to the site all the time, while it is only required on 1 action. So from this perspective I would like to avoid using cookie. But don't see a better of doing this over a regular HTTP. I don't consider IP/MAC address etc. So, with the context above, the questions is: how to anonymously identify a user and store that information on the client? Thanks.
