Server cache and SEO

[topchinaseo]

I have a question about server cache and seo. For example. www.chanel.com.cn , the server is in US, and uses China Cache to improve local Chinese users access speed, so what do you think this way will work for search engines spiders too? when a spider is crawlling the website, does the content it crawl on US server or China cache?

what's best practice for those kind of SEO on server side?

thanks

When you say cached on a china server, do you mean cached or a copy?

if you ping your domain from chin does it giove the same ip number as it would in the US?

anyhow google will crawl from the US so all should be fine.
