Invalid URI encoding with URLEncoder.encode()

[dumbbell]

The client uses URLEncoder.encode() to escape path segments in the created URLs. Unfortunately, this module produces invalid path segments: it transforms spaces to +. This is fine for query string, but not path segments.

Newer versions of Cowboy, which have a stricter URL parsing, leave the + characters alone. So when a user of this HTTP client wants to create eg. a vhost with a space in it, he ends up with a vhost with a +.
