#### 2.11`` Serving Files

(require web-server/dispatchers/dispatch-files)
| package: web-server-lib

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

> > procedure
> > (make |  | #:url->path url->path |  |  |  |
> > | [ | #:path->mime-type path->mime-type |  |  |  |
> > |  | #:indices indices]) |  | → |  | dispatcher/c
> url->path : url->path/c
> | path->mime-type |  | : |  | (path? . -> . (or/c false/c bytes)?)
> |  |  | = |  | (lambda (path) #f)
> 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.
