The authentication modules have been rewritten with support for dets, plain and mnesia authentication databases. There is also a new module called 'mod_secrity', which implements security event logging and notification. Both the mod_auth and mod_security modules have an API for the programmer that implements functions they will require to have full control over access restricted parts of a site. NOTE: The mod_auth_mnesia module does not implement the API previously found there, please see the mod_auth documentation.

The HTTP server now experimentaly supports persistent connections (as defined in RFC2068). This is the first step towards HTTP/1.1 support. Enabling this feature may greatly improve performance, as the server then uses the same TCP connection for more than one HTTP request. Two new configuration directives are defined for httpd_core: KeepAlive max-requests KeepAliveTimeout seconds
