This simple module serves files from the local disk over HTTP.
Options:
\begin{description}
\titem{docroot} \ind{options!docroot}
Directory to serve the files.
\titem{accesslog} \ind{options!accesslog}
File to log accesses using an Apache-like format.
No log will be recorded if this option is not specified.
\titem{directory\_indices} \ind{options!directoryindices}
Indicate one or more directory index files, similarly to Apache's
DirectoryIndex variable. When a web request hits a directory
instead of a regular file, those directory indices are looked in
order, and the first one found is returned.
\end{description}
This example configuration will serve the files from
the local directory \verb|/var/www|
in the address \verb|http://example.org:5280/pub/archive/|.
To use this module you must enable it:
\begin{verbatim}
{modules,
[
...
{mod_http_fileserver, [
{docroot, "/var/www"},
{directory_indices, ["index.html", "main.htm"]},
{accesslog, "/var/log/ejabberd/access.log"}
]
},
...
]}.
\end{verbatim}
And define it as a handler in the HTTP service:
\begin{verbatim}
{listen,
[
...
{5280, ejabberd_http, [
...
{request_handlers, [
...
{["pub", "archive"], mod_http_fileserver},
