Notes:
|
By default, URL filtering response pages explain why a
requested URL can't be accessed and show the user's IP address, the requested URL,
and the URL category. You can customize the response pages to meet the needs of your
enterprise. For example, you can change the message displayed to users, add
corporate branding, or link to an acceptable use policy.
To customize a page, export it from a platform and modify it in a text editor. You
can make updates using the provided response page variables and references.
Response page variables correspond to the specific user, URL, and category that was
blocked. Response page references enable the use of images, sounds, style sheets,
and links.
The Panorama™ web interface does not support the
export of response pages.
Custom response pages larger than the maximum supported size are not decrypted or displayed to
users. In PAN-OS 8.1.2 and earlier PAN-OS 8.1 releases, custom response pages on
a decrypted site can't exceed 8,191 bytes; the maximum size is 17,999 bytes in
PAN-OS 8.1.3 and later releases.
