Caching the uncacheable: CloudFlare's Railgun

So how does this work if you want to count the number of visitors, delivering customer specific versions of the site etc...? Does the bbc example even work because I can imagine that there multiple versions of the site depending on which IP is accessing BBC

I'm guessing the visitor IP still gets passed. This looks to be entirely synchronous, so everything would still work. The CDN just only has to fetch a delta of the page rather than the whole.

Well, one obvious thing with BBC News is that ads aren't shown for UK visitors but are for international visitors.
