Method: Gem::Net::HTTPHeader#each_capitalized_name

Defined in:
lib/rubygems/net-http/lib/net/http/header.rb

#each_capitalized_name ⇒ Object

Calls the block with each capitalized field name:

res = Gem::Net::HTTP.get_response(hostname, '/todos/1')
res.each_capitalized_name do |key|
  p key if key.start_with?('C')
end

Output:

"Content-Type"
"Connection"
"Cache-Control"
"Cf-Cache-Status"
"Cf-Ray"

The capitalization is system-dependent; see Case Mapping.

Returns an enumerator if no block is given.
