ejabberd-mod-muc-log-http 0.2015.10.02~dfsg0-1 (amd64 binary) in ubuntu xenial

 This module serves the directory containing MUC logs already configured on
 mod_muc_log. This way there is no need to set up a separate web server to
 allow your users to view the MUC logs. It is a small modification of
 mod_http_fileserver, customized for log serving.
