Web Components blocking. You can filter the following Web Component types: Proxy, Java,
ActiveX, and Cookies. For example, by enabling Java filtering, "Java" files will be blocked.
Certain commonly used web components can be blocked for increased security. Some of these
components are can be used by malicious websites to infect computers that access them.
Proxy. A proxy server (or simply, proxy) allows computers to route connections to other
computers through the proxy, thus circumventing certain firewall rules. For example, if
connections to a specific IP address are blocked by a firewall rule, the requests can be
routed through a proxy that is not blocked by the rule, rendering the restriction ineffective.
Enabling this feature blocks proxy servers.
Java. Blocks java applets from being downloaded from pages that contain them. Java
applets are small programs embedded in web pages that enable dynamic functionality of
the page. A malicious applet can be used to compromise or infect computers. Enabling this
setting blocks Java applets from being downloaded.
ActiveX. Similar to Java applets, ActiveX controls install on a Windows computer
running Internet Explorer. A malicious ActiveX control can be used to compromise or
infect computers. Enabling this setting blocks ActiveX applets from being downloaded.

newsgroup to be blocked by the VPN firewall.
You can apply the keywords to one or more groups. Requests from the PCs in the groups for
which keyword blocking has been enabled will be blocked. Blocking does not occur for the
PCs that are in the groups for which keyword blocking has not been enabled.
You can bypass Keyword blocking for trusted domains by adding the exact matching domain
to the list of Trusted Domains. Access to the domains or keywords on this list by PCs, even
those in the groups for which keyword blocking has been enabled, will still be allowed without
any blocking.
