Chapter 36 Content Filtering Table 171 Configuration > Anti-X > Content Filter > Filter Profile > Customization LABEL DESCRIPTION Allow Web traffic for trusted web sites only When this box is selected, the ZyWALL blocks Web access to sites that are not on the Trusted Web Sites list.

When you download a page containing a restricted feature, that part of the web page will appear blank or grayed out.

When you visit an ActiveX web site, ActiveX controls are downloaded to your browser, where they remain in case you visit the site again. Java Java is a programming language and development environment for building downloadable Web components or Internet and intranet business applications of all kinds. Cookies Cookies are files stored on a computer's hard drive. Some web servers use them to track usage and provide service based on ID. Web Proxy A server that acts as an intermediary between a user and the Internet to provide security, administrative control, and caching service.
