.recursively_generate_query(component, prefix, pairs = []) ⇒ Object

This method is based on the monkey patched method: Ethon::Easy::Queryable#recursively_generate_pairs

The monkey patch was needed to pass Array params without an index.

The problem is described in typhoeus/typhoeus issue #320: github.com/typhoeus/typhoeus/issues/320

The fix is described in dylanfareed/ethon commit 548033a: github.com/dylanfareed/ethon/commit/548033a8557a48203b7d49f3f98812bd79bc05e4
