Hi,

I am trying to implement something done in almost any website out there : a 'ilike' button (like Facebook) that does not require user authetication to be used for any article of my website written in Grails.

I don't want to use any external solution, so I need to implement it myself (or use a grails plugin).

So my question is : What does it take to implement this 'ilike' button and prevent users from cheating? For instance, do I need to store local cookies (I suppose yes)? Do I need to check the session ID and IP of the HTTP request?

Any well-known implementation are welcomed.

Thank you very much for your help.
