I am currently testing a CDN. It is one of the big ones.
What I noticed is that no-cache headers are being sent by the CDN.
I find that highly annoying.
The bandwidth is not cheap. I'll need about 5 mbps to serve ads. It would cost me $120 dollar a month to serve those ads from the CDN.
For that kind of money, I could get a dedicated ad server with 10mbps.
And I could even save bandwidth if the right headers are used.
I guess I'll only use the CDN for small files and keep serving those ads from my own server.
Anybody using CDNs? Anybody else annoyed that CDNs send no-cache headers?
