Captcha bot protection and URL Rewrite

Captcha-based bot protection modes and URL Rewrite for single-page apps.

Choose your Standard Bot Protection mode

Standard Bot Protection now supports a Captcha challenge in addition to the existing silent Proof of Work check. Choose which mode to run — captcha, pow, or both (the default) — and configure how long a visitor stays cleared after passing a challenge with a new Captcha clearance duration setting (default 1h).

See Security for configuration details.

URL Rewrite

You can now rewrite an incoming request's URL to a fixed path before it's matched against your rules again. Common uses include routing everything under a path to a single-page app's entry point, or silently redirecting a retired page to its replacement without a client-visible redirect.

See General for configuration details and constraints.
