So I can see plenty of information about what to do with Magento and APC for single storefronts but how about multi stores?
I have 1 local.xml files that has 3 storefronts on that are on 3 different domains. In my local.xml I have the following:
<cache>
<backend>apc</backend>
<prefix>sitename_</prefix>
</cache>
Is this correct or should there be different prefixes for the different storefronts? I'm inclined to say that way I have done is correct but could anyone else confirm either way?
