What would it matter if they did cache the page? I don't see how this tag helps your position in the SERPs???? And that is what this thread is about I think???
True, this meta tag is not really related to seo and i overlooked that part of the question. You seem to be really bothered by it, Compar...
I'm not bothered. My question or comment had two parts. The first was "what would it matter....." and while I was thinking about that it occurred to me that the entire comment was slightly off topic. Just in case some newbie thought this was a SEO or SERP suggestion. So I still am interested why would it matter if Google cached these frequently changing pages?
