XF Surge Guard - Xenforo 2 1.0.4

XF Surge Guard reduces wasted XenForo load from unauthenticated guest and bot request patterns before they keep consuming PHP, MySQL, and XenForo resources.

It is built for a specific problem:
A guest, bot, crawler, scanner, or broken link repeatedly hits dynamic XenForo URLs that produce missing routes, 404s, permission failures, or other low-value responses. XenForo still has to boot, route, dispatch, query, and render a response for traffic that has already proven to be wasteful.

XF Surge Guard watches eligible unauthenticated requests and, in Guard mode, temporarily exports high-confidence waste patterns to a lightweight early bootstrap guard.

On later matching requests, the guard can answer before XenForo fully boots.

That means less wasted work for XenForo, PHP, and MySQL.

What it does
XF Surge Guard observes eligible unauthenticated GET/HEAD requests and detects guest traffic waste such as:

• Soft 404 guest requests
• Missing dynamic XenForo paths
• Invalid route requests
• Failure-heavy guest traffic bursts
• Repeated bad-path requests
• Scanner-style probes and broken external links
• High-confidence request patterns that are safe to temporarily short-circuit

When a pattern qualifies, the add-on exports a short-lived rule to a lightweight early bootstrap guard loaded from XenForo’s src/config.php.

On later matching requests, the guard can return a tiny early response before XenForo performs expensive routing, controller dispatch, template rendering, session work, or database-heavy operations.
