H3C MSR Series Command Reference

369
Usage guidelines
Portal redirects all HTTP requests except HTTP requests that match portal-free rules to the portal
Web server, which might overload the server.
Portal safe-redirect filters HTTP requests by HTTP request method, browser type (in HTTP User
Agent), and destination URL, and redirects only the permitted HTTP requests.
As a best practice to avoid server overload and improve security, enable portal safe-redirect on the
device.
Examples
# Enable the portal safe-redirect feature.
<Sysname> system-view
[Sysname] portal safe-redirect enable
Related commands

extension.
