I'm new to CDNs. I have dynamically generated pages that have a 30 minute expiry on each URL, and I want these to be edge cached. Are there any CDNs that can just act as a proxy cache and when a user requests a page, the CDN cache it for the next user in the same region?

EDIT: The CDNs I've read about all seem to require you to have users request the resource from a url that points to their domain name (eg. E123456.cloudfront.net). This is fine for images and videos because the user doesn't actually see that in their address bar. Since I'm caching the html pages, the user needs to be able to request it from the normal location (eg. www.mydomain.com/page1). I'm wondering if there are CDNs that allow this.

EDIT: Can anyone give me some names of a few CDNs that don't require changing urls?

Unless I've entirely misread your question that's EXACTLY what a CDN does, actually very little other than that to be honest.

  • Cool, I've never used one before, I've just seen the people using amazon aws, and it seems they have to specify an s3.aws url instead of things happening seamlessly.

  • Not a problem, nobody's born knowing this stuff right :) It seems like you've got the right idea and are on the right track, come back to us as you need ok.

  • @Chopper I'm looking at Amazon Cloudfront (aws.amazon.com/cloudfront/faqs), and it seems that to get it to distribute from the edge cache, you need to use a special url you get from an api call (eg E123456.cloudfront.net). This wouldn't work for dynamically generated html since users would have to access it at www.mydomain.com/page, and couldn't access it at a cloudfront url.

  • Very often CDN users have to 'tickle' their CDN to call down content into cache, not doing so can often mean content is de-cached before you want it to be. In fact there's quite an industry out there just to keep content inside CDN caches. Not a CF expert though sorry, in fact I build my own CDNs as part of my job so don't know CF at all sorry.

  • @Chopper - So, other CDNs would not require that I use a different url for it to be edge cached? That's my main concern.
