Middleware for rails app that adds checksum of JSON in the response headers which can help client to realize when JSON has changed

Add the following to your application.rb

  require 'apipie/middleware/checksum_in_headers'
  # Add JSON checksum in headers for smarter caching
  config.middleware.use "Apipie::Middleware::ChecksumInHeaders"

And in your apipie initializer allow checksum calculation

  Apipie.configuration.update_checksum = true

and reload documentation

  Apipie.reload_documentation

By default the header is added to requests on /api and /apipie only It can be changed with

  Apipie.configuration.checksum_path = ['/prefix/api']

If set to nil the header is added always
