Web Filters

| Web filters can monitor, evaluate, and intercept HTTP communication between an internal network and the Internet. Web filters are loaded when the Microsoft Firewall service is started. After being loaded, Web filters can be configured to receive special filter event notifications that occur with each HTTP request and response. ISA Server features can be extended by installing Web filters developed by other vendors.
