Http-_headers?

Ruby

IANAE: Ruby or http.
Re: Having issues with http header references.

Regarding the keys in headers:
Firefox sends Capitalized-Hyphenated.
Does Event machine UPCASE?
Generally, is underscore used over hyphen?
Hyphen appears in the RFC headers.
Rack uses lower.case with .period.

Quick look at some gems shows diversity.
Diversity is great, but.

Kirk notes that http headers references in hashname are best as
Constants for performance.
Is there a gem which parses the source of gems, normalising header
references?

It doesn’t matter. HTTP headers are case-insensitive.

Generally, is underscore used over hyphen?

Never. That would be an entirely different header.

These are not HTTP headers, but private data to avoid confusion or
overlap with HTTP headers.

While there are many generic techniques for improving performance of
ruby code such as using constants you should focus on improving
performance based on measurements instead of blindly making changes.

This is not necessary.

Thanks Eric,
I was in a tight corner there for a while.
There are larger issues being addressed:

Helpful to know.

Did this sound serious?! :wink:
