Chapter 16      Notifying End Users
Notification Page Types
Also, where an embedded URL is of the form: 
<protocol>://<domain-name>/<directory path>/
 then 
all sub-files and sub-directories under that directory path on the host will also be exempted from all 
scanning. 
For example, if the following URL is embedded: 
http://www.example.com/gallery2/
 URLs such as 
http://www.example.com/gallery2/main.php
 will also be treated as exempt.
This allows administrators to create a more sophisticated page with embedded content so long as the 
embedded content is relative to the initial URL. However, administrators should also take care when 
deciding which paths to include as links and custom logos.
Notification Page Types
Users accessing the Internet sometimes cannot access the server they want. By default, the Web Proxy 
displays a notification page informing users they were blocked and the reason for the block. This section 
lists and describes all possible notification pages a user might see while accessing the Internet.
Possible reasons that cause notification pages to appear include the following:
  •
End-user notification pages are enabled and the user accessed the Internet in a way that violated an 
Access Policy.
  •
End-user notification pages are configured to allow end-users to report misclassified pages to Cisco 
and the user reported a misclassified page.
  •
The end-user acknowledgement page is enabled and the user accessed the Internet for the first time 
since the timeout period expired.
  •
The Web Security appliance could not access the server requested due to an external error, such as 
DNS failure or an unavailable server.
Most notification pages display a different set of codes that may help administrators or Cisco IronPort 
Customer Support troubleshoot any potential problem. Some codes are for Cisco internal use only. The 
different codes that might appear in the notification pages are the same as the variables you can include 
in customized notification pages, as shown in 
 describes the different notification pages users might encounter.
