Thanks for the fast reply.

>1. The static content - jpg, png, tiff, etc. It looks as though you are serving them your backend and caching them. Are they also being built on demand dynamically? If not, then why csche them? Why not deploy them to nginx and serve them directly?

There is a huge part of static content that is stored on a shared filesystem, which is delivered from backend. Unfortunately I don't have any chance to change this for now.

>2. The text content - is this fragments of html that don’t have names that end in html?

Yes it seem's so.

Cheers,
