Method: Addressable::URI#route_from
- Defined in:
- lib/addressable/uri.rb
#route_from(uri) ⇒ Addressable::URI
Returns the shortest normalized relative form of this URI that uses the supplied URI as a base for resolution. Returns an absolute URI if necessary. This is effectively the opposite of route_to
.
