5.11 Serving Files

(require web-server/dispatchers/dispatch-files)

The web-server/dispatchers/dispatch-files module allows files to be served. It defines a dispatcher construction procedure.

(make   #:url->path url->path            [ #:path->mime-type path->mime-type             #:indices indices])   →   dispatcher?

url->path : url->path?

path->mime-type   :   (path? . -> . bytes?)       =   (lambda (path) TEXT/HTML-MIME-TYPE)

indices : (listof string?) = (list "index.html" "index.htm")

Uses url->path to extract a path from the URL in the request object. If this path does not exist, then the dispatcher does not apply and next-dispatcher is invoked. If the path is a directory, then the indices are checked in order for an index file to serve. In that case, or in the case of a path that is a file already, path->mime-type is consulted for the MIME Type of the path. The file is then streamed out the connection object.

This dispatcher supports HTTP Range GET requests and HEAD requests.
