B.2 An Overview of URL Content Filtering
The URL content filtering facility in the Vigor series of broadband
security routers inspects every URL string in the HTTP request initiated
inside against the keyword list. If the entire or part of the URL string
(for instance, http://www.draytek.com, as shown above) matches any
activated keyword, its associated HTTP request will be blocked by the
Vigor router and a syslog message will be automatically sent to the
syslog client. Also any request which tries to retrieve the malicious
code will be discarded by the Vigor router. Similarly, a syslog message
will be sent to the syslog client.
The URL content filtering facility prevents users from accessing
inappropriate websites whose URL strings are identified as prohibition.
You must clear your browser cache first so that the URL content
filtering facility can work properly on a web page that you visited
before
