After
completing these steps, the firewall executes the JavaScript whenever
an end user searches. For example, suppose a student’s Bing SafeSearch
preference is set to
Off
when they
research a concept likely to yield inappropriate results. Detecting
the safe search preference, the firewall appends
&adlt=strict
to
the search query URL. Then, the search engine displays appropriate
results and the SafeSearch preference changes to
Strict
.
