Firewall Block Response specifies how the Shield plugin will respond when the firewall detects malicious data.
Firewall Block Response options explanations
Option: Block Response
This option helps you to choose how the firewall responds when it blocks a request.
You have 4 possible responses:
- Die With Message - Kill (end) the running PHP process and display a friendly message
- Die - Immediately kill (end) the running PHP process
- Redirect To Home Page - Redirect the web request to the homepage
- Return 404 - Redirect the web request to a 404 page
Whichever you choose is down to your personal preference. We recommend dying with a message (the default) so you know what might have occurred when the firewall blocks you. (See the screenshot below)
Option: Send Email Report
This option, when enabled will send the administrators an email notifying them of a firewall block incident.
Important: Use this option with caution - if you get hit by automated bots you may send out too many emails and you could get blocked by your host.
