Configuring Website Access Control List
Blocking an URL category will block all websites that belong to this category. You
can specify the website exceptions in the website access control list. The website
exceptions will override the URL category settings in the same profile.
NOTE Up to 32 website exceptions can be configured for each Web URL Filtering policy
profile.
STEP 1 In the Specify URLs or URL keywords you want to permit or deny area, click
Edit.
The Policy Profile - Add/Edit window opens.
STEP 2 To add a website access rule, click Add.
Other options: To edit an entry, click the Edit (pencil) icon. To delete an entry, click
the Delete (x) icon. To delete all entries, click Delete All.
The Website Access Control Rule - Add/Edit window opens.
STEP 3 Enter the following information:
• Enable Content Filter URL: Click On to enable the website access rule, or
click Off to create only the website access rule.
• URL: Enter the domain name or URL keyword of a website that you want to
permit or block.
• Match Type: Specify the method for applying this rule:
- Domain: Permit or deny the HTTP access of a website that fully matches
the domain name that you entered in the URL field.
For example, if you enter yahoo.com in the URL field, then it can match the
website http://yahoo.com/*, but cannot match the website
http://*.yahoo.com.uk/*.
- URL Keyword: Permit or deny the HTTP access of a website that
contains the keyword that you entered in the URL field.
For example, if you enter yahoo in the URL field, then it can match the
websites such as www.yahoo.com, tw.yahoo.com, www.yahoo.com.uk,
and www.yahoo.co.jp.
• Action: Choose Permit to permit access, or choose Block to block access.
