Is it possible for my cocoa app to block access to a specific web

is there any open source firewalls for OSX?
Mac OS X ships with ipfw installed as a kernel extension, although there
are no rules installed by default. There is a socket interface and a
command-line tool (see man ipfw for details) for configuring it. There
are a number of third-party apps available for graphically configuring
it, and it can also be administered using the tools included with Mac OS
X Server.
If you wish to block access to a specific web URL, however, a
client-machine firewall may or may not be the appropriate means,
depending on your goal. There are many other approaches, depending on
your aims, network configuration, etc., and there is an extensive body
of literature on the topic.
