Using W3 Total Cache's CDN option with DreamObjects


W3 Total Cache offers several tools to boost the performance of your WordPress site. One of these tools is it's CDN integration option. Using this, it is possible to use DreamObjects content with W3 Total Cache.

The plugin asks for a CDN type and while DreamObjects isn't in the list, it is possible to specify an S3-compatible service (which DreamObjects qualifies as).
