SWI-Prolog -- http

Availability::- use_module(library(http/http_dispatch)).

Redirect to a new location. The argument order, using the Request as last argument, allows for calling this directly from the handler declaration:

:- http_handler(root(.),
                http_redirect(moved, myapp('index.html')),
                []).

`How`	is one of `moved`, `moved_temporary` or `see_other`
`To`	is an atom, a aliased path as defined by http_absolute_location/3. or a term `location_by_id(Id)` or its abbreviations `#(Id)` or `#(Id)+Parameters`. If `To` is not absolute, it is resolved relative to the current location.
