URL address management

The URL address management allows you to specify HTTP addresses to block, allow or exclude from checking. Websites in the List of blocked addresses will not be accessible unless they are also included in the List of allowed addresses. Websites in the List of addresses excluded from checking are not scanned for malicious code when accessed. SSL/TLS protocol filtering must be enabled if you want to filter HTTPS addresses in addition to HTTP web pages. Otherwise, only the domains of HTTPS sites that you have visited will be added, the full URL will not be.

One list of blocked addresses may contain addresses from some external public blacklist, and a second one may contain your own blacklist, which makes it easier to update the external list while keeping yours intact.

Click Edit and Add to create a new address list in addition to the pre-defined ones. This can be useful if you want to logically split different groups of addresses. By default, the following three lists are available:

•List of addresses excluded from checking - No checking for malicious code will be performed for any address added to this list.

•List of allowed addresses - If Allow access only to HTTP addresses in the list of allowed addresses is enabled and the list of blocked addresses contains * (match everything), the user will be allowed to access addresses specified in this list only. The addresses in this list are allowed even if they are included in the list of blocked addresses.

•List of blocked addresses - The user will not be allowed to access addresses specified in this list unless they also occur in the list of allowed addresses.

You can Add a new URL address into the list. You can also enter multiple values with separator. Click Edit to modify an existing address in the list, or Delete to delete it. Deleting is only possible for addresses created with Add, not the ones that were imported.

In all lists, the special symbols * (asterisk) and ? (question mark) can be used. The asterisk represents any number or character, while the question mark represents any one character. Particular care should be taken when specifying excluded addresses because the list should only contain trusted and safe addresses. Similarly, it is necessary to ensure that the symbols * and ? are used correctly in this list.
