Resolution
Create and save a clear-text ANSI file containing the following code:
Note: For this example, the file is saved as "url-block-page.txt" and used as the HTTP Redirect for a Block Page. For https sites, use https://www.example.com/ in the HTML code.
Select the Response Page to customize (GUI: Device > Response Pages)
Browse your computer and add the plain text file you just saved, to Destination: shared
Click OK. A 'shared' Location will be listed on the Response page, which means the Custom Response Page has been loaded.
Commit to complete the configuration. Blocked pages will now be redirected to http://www.example.com/
