Method: RestClient::Request#stringify_headers

Defined in:
lib/restclient/request.rb

#stringify_headers(headers) ⇒ Object

Return a hash of headers whose keys are capitalized strings

BUG: stringify_headers does not fix the capitalization of headers that are already Strings. Leaving this behavior as is for now for backwards compatibility. github.com/rest-client/rest-client/issues/599
