APACHE mod_auth limit number of users connecting at the same time

Question

im trying to password protect a directory and its files i know its possible to generate temporary download links with php but the subfolders and files are generated dynamicly its a little hard for me to use php. setting user/pass with mod_auth is Good but is there any way to limit the number of connections at the same time ? or log connections for each username somehow? ex:

username:password :: 255.255.255.255 :: 2014/6/1

maybe another module can do that ?

Make them FTP URLs and use a connection-limiting FTP server such as FileZilla Server.
