Service providers may need to apply network-wide URL filtering policies and either allow or prevent some content for all subscribers. AA supports both allow-list and deny-list local URL-list filtering.
Local URL-list filtering is performed on both HTTP and HTTPS traffic.
The system supports both unencrypted and OpenSSL 3DES encrypted file formats to protect the contents of the list.
Operators can specify the size of the URL list to be filtered. The size can be set to either standard or extended. If the specified URL list is configured as extended, support is provided for filtering on a larger number of URLs.
The hostnames of a local list may contain wildcards.
The following characters are considered invalid and result in a failure to load the URL list:
non-printable ASCII characters other than \n and \r
space characters in the URL
When specifying a URL, do not include schema such as https:// or ftp://. The schema http:// is allowed but is not necessary.
The following is an example of URL list file content:
# Comment line for domain1 URL not using http:// schema
www.domain1.com/URI1
# Comment line for domain2 URL using http:// schema
http://domain2.com/URI2
