WinpkFilter Samples

Windows Packet Filter Kit: Samples

WWWCensor

This is a simple packet content filtering sample. It accepts a single word or phrase as input and drops every HTTP packet where it finds the specified pattern. An example, if you start "wwwcensor.exe porn" the application will block access to any web site which contains "porn" as part of the URL also no pages containing the word porn will be displayed in browser.
