Expected Behavior

It would be great to have a configurable and client-driven fallback mechanism for template resolution; for example, if there's both templates/feed.html and templates/feed.xml, have serve up feed.html to web browsers and feed.xml to RSS readers.

Current Behavior

Content negotiation is based on a hard-coded priority system that's universal to all templates, and disregards the client's request.


Very useful for supporting more dynamism in templates and more user-friendly feed presentation and so on.

Thoughts: have some sort of configurable mapping (ideally on a per-category and/or per-template basis) that sets the content-type for each extension, and also a default q-value for use with the Accept: header (i.e. set a default priority internally but let the user-agent override it on a per-type basis) and then choose the highest q-value for which template to use.

This mapping file could also be where we can configure other headers for the response, such as cache-control or content-type, rather than continuing to use the crappy hard-coded mapping in
