Apache is the most popular webserver on the Internet, quite possibly the best in terms of security, functionality, efficiency, and speed.
Changes: Two security updates - Closed autoindex /?M=D directory listing hole reported in bugtraq id 3009 which returned directory listings if multiviews and indexes are enabled.. Made split-logfile use the default logfile name if "/" or "\" are present in the virtual host name. This prevents the possible use of specially crafted virtual host names in some configurations to allow writing to any .log file on the system. Fixed quite a few minor bugs. Changelog available here.
