This option lets you manually enter what web and ftp sites your users are denied or allowed access to. The Server also supports web access control through an External Proxy Filter service. It should be noted that if you use both of these methods together, the external filter will always block URL's upstream of the local filter.
There are two ways that these menus can be configured, as a list of sites to block with exceptions, or as a list of sites to allow.
Configuring a list of Sites to Block, with possible exceptions
By entering URL's, or partial URL's, into the table of 'Web Sites
to Block Access to' you can block anything from individual pages to
complete protocols. For example, entering the partial URL "http:"
will block all web (http) access, whereas "http://www.sex"
will block access to all
sites beginning with the partial URL specified.
This would include the URL's "http://www.sex.com" and "http://www.sextet.co.uk"
You can also specify FTP URL's, which begin with "ftp://".
Exceptions to the Block List can be specified by making entries in the 'Exceptions to Block List' table. For example if you specify "http://www.sex" in the Block List, but want to allow access to the site "http://www.sextet.co.uk", this URL, or a sufficient portion of it, can be put in the Exceptions table to achieve this.
Configuring an exclusive list of Sites to which access is allowed
By placing the entries "http:" and "ftp:"
in the table of 'Web Sites to Block Access to', the ONLY
sites that users can access will be those in the 'Exceptions to Block
List' table.
