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, 
you 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:
  •
IronPort notification pages are enabled and the user accessed the Internet in 
a way that violated an Access Policy.
  •
IronPort notification pages are configured to allow end-users to report 
misclassified pages to IronPort 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 HTTPS Proxy is enabled and the appliance is configured to drop HTTPS 
requests to servers with invalid certificates.
  •
The Web Security appliance could not access the server requested due to an 
external error, such as DNS failure or an unavailable server.
