Is there a way to cache datasets on the client side using Python/Anaconda/Bokeh?

I have a python Bokeh project and generating the plots works nicely but it takes a while. As I understood the Bokeh server generates a model based on the data which is pushed (or pulled) and then the graph generation occurs on the client side using Javascript. Is there a way to instruct Bokeh to cache as much as possible on the client side? ideally do this per document. Is there an API for this? Are there other caching strategies available using Bokeh?
