Prevent replacement messages to be indexed by search engines
Description
The replacement messages could be HTML pages and can be customized.
A search engine robot could index a HTML replacement message returned by a FortiGate that is configured to reply with a notification page.
Solution
Configuration Steps
- Open the FortiGate Web GUI
- Go to System > Config > Replacement Messages
- Enable the extended view
- Look for the pages using HTML. It starts with the following line:<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
- To prevent search engine indexation, the robots meta tag must be added after the <head> header:
<head>
<meta name="robots" content="noindex,nofollow"/>
