Middleware function to serve static files

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.

Value

Handler function.
