class Roda
module RodaPlugins
# The head plugin attempts to automatically handle HEAD requests,
# by treating them as GET requests and returning an empty body
# without modifying the response status or response headers.
#
# So for the following routes,
#
# route do |r|
# r.root do
# 'root'
# end
#
# r.get 'a' do
# 'a'
# end
#
# r.is 'b', :method=>[:get, :post] do
# 'b'
# end
# end
#
# HEAD requests for +/+, +/a+, and +/b+ will all return 200 status
# with an empty body.

# Always use an empty response body for head requests, with a
# content length of 0.
