cache.client (when no cache_model is passed) just sets headers (that's the idea at the bottom). When you pass a cache_model, it sets headers AND cache the results (and that's the "idea at the top").
cache.client was created in the first place to avoid having to set headers repeatedly. There's no "improvement" to look for caching the results of a download() ^_^ On Saturday, April 6, 2013 3:23:22 PM UTC+2, Massimo Di Pierro wrote: > > Does that work for download?
