Overview

Handles multiple URL params with the same name

Europeana’s APIs expect params with the same name to appear in URL queries like ‘?qf=this&qf=that`, but Faraday constructs them the Rack/Rails way, like `?qf[]=this&qf=that`. This middleware constructs them to the former format, using `Rack::Utils.build_query`.
