Best practice to save data for anonymous users?
<p>I'm building a web app and i'd like to allow anonymous users to use it and to save some data without signing up.</p>

<p>let's assume the user save a list of favorites image urls without singing up.</p>

<p>now i'm using this way: I save those favs in db and then i save the user's ip address
so every time the user go back he can see his past favs</p>

<p>of course this is a temp solution</p>

<p>what's the best way to associate that list to a specific user?
save it in a cookie?
some hybrid solution?</p>
