Firstly, if you wish to, you can configure the file updating interval (i.e. the time period that must pass before the
device can ask the server for the file again). To do this, enter the [<config>] tag and, in the following line, the
value required for the updating period. In this example, the device requests the file every hour (3600 seconds).
If you don’t specify any value, the default updating interval is 1 day.

Subsequently, you can enter the http error page that you want to be displayed in cases where there has been
an attempt to enter an unwanted page. To do this, enter the error page after the [<template>] tag.

Lastly, you need to enter the configuration to execute Web page filtering (whether through content or through its
url address). To do this you can enter:
- the list of url addresses (or IP addresses) belonging to pages considered to
have unwanted contents, after the [<urls>] tag.
- the list of words considered as unwanted content, after the [<words>] tag.
- the list of url addresses belonging to pages that are considered safe (i.e. those
that are not going to be searched through to see if they contain unwanted
words), after the [<white-urls>] tag
Note
Keep in mind that, for content filtering to work, the content of the requested page cannot be encoded.
To ensure that this doesn’t happen, use the NAT http force-identity-encoding command (please see
manual
bintec Dm788-I New NAT Protocola).
