Device > Response Pages
Custom response pages are the web pages that display when a user tries to access a URL. You can provide a custom HTML message that is downloaded and displayed instead of the requested web page or file.
Each virtual system can have its own custom response pages. The following table describes the types of custom response pages that support customer messages.
The firewall displays this page so that users can enter login credentials to access services that are subject to Authentication policy rules (see Policies > Authentication). Enter a message that tells users how to respond to this authentication challenge. The firewall authenticates users based on the Authentication Profile specified in the authentication enforcement object assigned to an Authentication rule (see Objects > Authentication).
Tip: 
You can display unique authentication instructions for each Authentication rule by entering a Message in the associated authentication enforcement object. The message defined in the object overrides the message defined in the Authentication Portal Comfort Page.
Select Objects > Security Profiles > URL Filtering to enable credential detection and control credential submissions to web pages based on URL category.
