Chapter 6: Configuring Application Defenses
Creating Web Cache Application Defenses
3 [Conditional] To slow the download process for filtered sites, in the Delay
field, type the amount of time (in seconds) that you want to delay the Web
page display.
Delaying the download time discourages users from browsing certain sites
because it takes longer for those pages to be displayed. Valid values are
from 1–999.
Note: The Delay field applies to ALL categories in a rule that are set to Delay.
For example, if you have set Chat, Entertainment, and Art/Culture to delay, and
enter 30 seconds in the Delay field, sites that fall into any of the three categories
will be delayed by 30 seconds.
4 To deny Web access if a user attempts to access a site using an IP address
rather than a URL, select the Deny IP Addresses check box. Secure
Computing recommends enabling this check box.
5 To deny unclassified personal pages, select the Deny Unclassified
Personal Pages check box.
Note: Unclassified personal pages are pages that consist of uncategorized
URLs that contain a tilde, such as www.rootsweb.com/~wgnorway/. This
option does not refer to the Personal Pages category. It only refers to pages
that contain a tilde (~), as described above.
6 Click the Save icon to save your changes when you are finished configuring
an Application Defense.
Modifying a SmartFilter category
When you select a SmartFilter category and click Modify in the SmartFilter tab,
the SmartFilter Modification window appears. This window enables you to
change the settings for the selected SmartFilter category. The Category field in
the top portion of the window displays the SmartFilter category you selected for
modification. Follow the steps below.
1 In the Permission field, specify whether access to the selected SmartFilter
category will be allowed or denied by selecting the appropriate option from
the drop-down list.
2 In the Special Handling field, specify whether SmartFilter will process Web
requests to this category in a special manner. Valid options are:
• None—No special handling is performed.
• Coach—A predefined message is displayed to users informing them
that the site has been filtered, but allows them to proceed at their own
risk. The predefined message can be modified by editing the
/usr/local/squid/etc/errors/ERR_SCC_SMARTFILTER_COACH file.
Note: The Coaching feature works with all Internet Explorer browsers and
with Netscape browsers at version 6.0 or greater.
