Wednesday, 07 January 2009 AllegroSurf is a web accelerating, content filtering, proxy server! AllegroSurf allows you to share a single Internet connection with multiple computers on a LAN, while protecting users from unwanted content and increasing overall Internet speed. It is the perfect tool for network administrators, school administrators, or for personal use. AllegroSurf does not require a dedicated server to run. It simply needs to be installed on the computer with the physical connection to the Internet where it runs in the background to share this connection with the rest of the network.
