How does the SnapGear URL filtering module work?
SnapGear administrators create a filtering policy for their organization that resides locally on each SnapGear appliance. SnapGear administrators determine the types of URLs they want to allow or block and create their policy from a set of predetermined categories. The URL filtering engine runs as an Internet service on Webwasher Rating Servers around the world. The SnapGear appliance intercepts HTTP URL requests submitted by internal users and relays them to the Webwasher Rating Server. The Server quickly returns URL category data to the SnapGear appliance which then either blocks or allows user access to the requested Web site according to the local policy.
