RedShield Custom HTML Blocking Pages

A default RedShield blocking page appears as follows: 

This blocking page may be customised to support custom formatting. Customers should produce a custom HTML file and provide this to the RedShield team via a support ticket.

There are some design considerations which must be adhered to when producing a custom blocking page for your application: 

  • Files must be small (a few KB is OK) .
  • Files must contain no external references such as javascript, css or images (since these may also be blocked, and the page will fail to render correctly). The exception to this is references to non-shielded hostnames such as web analytics or other third party content
  • Files must contain something similar to the HTML sample below, which allows users to automatically raise a ticket in case of a false positive. The 19 digit web support ID must be included in the email, or otherwise transmitted electronically.
  • False Positive tickets may be raised on the customer support desk, instead of RedShield. However, they should automatically be forwarded to RedShield support to expedite remediation.
