Web Proxy replacement messages
The FortiGate unit sends Web Proxy replacement messages listed in the table below when a web proxy event occurs that is detected and matches the web proxy configuration. These replacement messages are web pages that appear within your web browser.
The following web proxy replacement messages require an identity-based security policy so that the web proxy is successful. You can also enable FTP-over-HTTP by selecting the FTP option in System > Network > Explicit Proxy.
