Documentation: What case do the keys in `request.headers` use?

The API docs page mentions that headers is a dictionary of headers but does not describe the format of the keys. Are they just as the caller specified them, or are they standardised to a particular case (such as first capital, rest lower case)? Thanks!

I’ve done some more testing, and the headers are definitely preserved (so my earlier comment on lowercasing is wrong). I’ve implemented a change that adds another field .normalizedHeaders, with header names lowercased.

The field is available to APIs deployed with claudia 1.6.0 (so api builder version is not that important). Here are the release notes: https://claudiajs.com/news/2016/08/02/claudia-1.6.0.html

Thank you! This is really useful when one needs to work with the headers.
