# Why do we need KudeURI? Because the URI.join method doing something stupid:
#
# URI.join('http://example.com/subpath', 'hello', '?token=secret')
# => “http://example.com/hello?token=secret”
#
# But what I expected is “http://example.com/subpath/hello?token=secret", the subpath is gone.
# By using SmartURI, you can handle the case above gracefully:
#
# SmartURI.join('http://example.com/subpath', 'hello', query: { token: secret })
# => "http://example.com/subpath/hello?token=secret"
