libpcap is only packet observer, it can not drop the packets.

Hi, If I want to write an application that prevents any TCP packets from being sent to a localhost web server, may I use libpcap for this purpose? To put the question differently, is libpcap: 1) an observer of the packet traffic (not what I'm looking for, since packets will still be sent to the localhost web server). 2) or does it actually sit in between all packet traffic? (this is what I'm looking for since I can then drop the packets that I want to drop). Thank you for your kind attention, S. - This is the tcpdump-workers list.
