Cache & Multi-domains

I think, you should avoid making cache of the page output in this case. You should use 'object cache' instead. Which will help you cache your php objects that might be causing the slow performance. And just don't cache the language files, and your problem will go away, hopefully. I don't see any sense to create a full rendered page cache when the app is dynamic. Only cache what is necessary.
