Do I really need to use Sockets and everything, All I want to do is have it where someone types in an internet address in any web browser on the computer, my app that is running behind the scenes will intercept any of those requests, and then if that address is in this database we have it will allow them to go there. At work we are just making this app to restrict others only to work related sites, so I quickly just want to make this thing. I just need to know how little snitch, intercepts the http(port 80) request and then after allowing it, the web browser shows it.

Read 'man divert' and 'man ipfw' for more information. As an added bonus you should be able to put much of the packet selection logic into an ipfw rule and only receive packets that your application is likely to find interesting.

I am sure you have heard of an App called, Little Snitch, well I want to write something similar but totally different. I want to intercept all but really only going to filter one type. So how would I get started on this, Im sure i need to use .kext s but dont know where to start. thanks, Matt _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
