Cisco Cisco Web Security Appliance S170 사용자 가이드

Enter the URL to which you want to redirect traffic in the Redirect To field for the custom category.

Submit and commit your changes.

In addition to using the Web Security appliance to block traffic to certain websites, you can also use it 
to warn users that a site does not meet the organization’s acceptable use policies and allow them to 
continue if they choose. You might want to warn users and allow them to continue if your organization 
wants to discourage its users from accessing certain sites, but does not want to or is not allowed by law 
to block access to those sites.

You can warn users and allow them to continue using one of the following methods:

Choose the Warn action for a URL category in an Access Policy group.

Enable the site content ratings feature and warn users that access adult content instead of blocking 
them. For more information on the site content ratings feature, see 

When users access a URL that is configured to warn and continue, they initially see an IronPort 
notification page with a warning about accessing sites of this category or content. The end-user URL 
filtering warning page includes the following elements:

Default warning text provided by Cisco

Custom text provided by the Web Security appliance administrator (optional)

Notification code listing the invoked Access Policy and the URL category being warned or the safe 
browsing scanning verdict.

A hypertext link to the originally requested URL

Users are tracked in the access log by user name if authentication has made a user name available, and 
tracked by IP address if no user name is available.

When you use the warn and continue feature, you can configure the following settings that affect the 
end-user URL filtering warning page:

Time Between Warning. The Time Between Warning determines how often the Web Proxy displays 
the end-user URL filtering warning page for each URL category per user. Once a user clicks the 
continue link on the end-user URL filtering warning page, the Web Proxy considers that user to have 
acknowledged the warning for the time you enter for the Time Between Warning. This setting 
applies to users tracked by username and users tracked by IP address. You can specify any value 
from 30 to 2678400 seconds (one month). Default is 1 hour (3600 seconds).

Custom message. The custom message is text you enter that appears on every end-user URL 
filtering warning page. You might want to include text for the organization’s acceptable use policies, 
or include a link to a page that details the acceptable use policies. You can include some simple 
HTML tags to format the text. For example, you can change the color and size of the text, or make 
it italicized. See 

 for more information.
