#### 2.11`` 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/c

url->path : url->path/c

| 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.
