2.
As the above Figure 21-2 illustrates, someone (PC1_1) is browsing forbidden web pages on office hours. The contents of
the web pages may include stock markets, violence, or sex that will waste the bandwidth of the Internet access link while
degrading the efficiency of normal working hours. So, we wish to prohibit the user (PC1_1) from viewing the page on the
forbidden web site.

Remove the cookies, Java applet, Java scripts, ActiveX objects from the web pages.

Prevent users from connecting to the forbidden sites.
21.3 Methods

Setup content filtering for web objects such as cookies and Java applets.
