I am looking at setting the currency of a guest site visitor. I have the look up and currency retrieval working OK based on the individuals IP.
The problem i seem to face is how to cache the currency per site visitor and not set it for the whole site/all visitors.
A dump of craft->session shows no unique guest ids available.
Should i set a cookie for current user (IP address) and compare with cached IP?
Any slaps around the head welcome :)
