Database caching?

[RodG]

Glad you discovered this - dynamic sites do not play well with cloud services

Kobra! You should be ashamed of yourself for making such a simplistic comment such as this.

You/We could also say the *exact* same thing about the caching provided by all web browsers as well as all proxy servers that are implemented (often transparently) by almost every ISP on the planet.

A CDN is just another cache, and like all caches, they only cache static content.

This very busy ZenCart site appears to be playing very nicely with the CDN. As can be clearly seen, the bulk of the content on this dynamic site are the static images. The bandwidth saved and performance gained (by not having to server the requests from the master/host server are clearly quite significant.

In what way can this be considered as 'not playing well'?
