mod_tsunami is a module for apache 1.3.x which dynamically limits the number of httpd slots used per vhost. It is useful if you provide home pages hosting, and don't want one site to use all the ressources.

For example, if you limit every vhost to 3 httpd slots max, and if the requests currently in process are:

http://bart.foo.com/a.html
http://bart.foo.com/a.html
http://bart.foo.com/b.html
http://homer.foo.com/c.html

Requests matching http://bart.foo.com/* will be rejected with a 503 status until one of the requests above concerning bart.foo.com is finished. Requests matching http://homer.foo.com/* are not limited yet as their number is under the limit of httpd slots per vhost.

See INSTALL file for installation and configuration of mod_tsunami.
