mw_static: Middleware function to serve static files
Description
The content type of the response is set automatically from the
extension of the file. Note that this is a terminal middleware
handler function. If a file is served, then the rest of the handler
functions will not be called. If a file was not found, however,
the rest of the handlers are still called.
Usage
mw_static(root, set_headers = NULL)
Arguments
root
Root path of the served files. Everything under this
directory is served automatically. Directory lists are not currently
supports.
set_headers
Callback function to call before a file is served.
