Overview

Rack middleware, inspired by Rack::RelativeRedirect.

This middleware allows you to return a relative or absolute path your Location: response header. This was common practice in HTTP/1.0, but HTTP/1.1 requires a full URI in the Location: header. This middleware automatically translates your path to a full URI.

Differences with Rack::RelativeRedirect:

  • uses Rack::Request::base_url for creating absolute URIs.

  • the `Location:` header, if present, is always rectified, independent of the HTTP status code.
