Serve files from the directory Alias from the path-info from
Request. This predicate is used together with
file_search_path/2. Note that multiple clauses for the same
file_search_path alias can be used to merge files from different
physical locations onto the same HTTP directory. Note that the
handler must be declared as prefix. Below is an example
serving images from http://<host>/img/... from the directory
http/web/icons.
http:location(img, root(img), []).
user:file_search_path(icons, library('http/web/icons')).
:- http_handler(img(.), serve_files_in_directory(icons), [prefix]).
This predicate calls http_404/2 if the physical file cannot be
located. If the requested path-name is unsafe (i.e., points
outside the hierarchy defines by the file_search_path/2
declaration), this handlers returns a 403 Forbidden page.
