HAProxy Manager Build and Push / Build-and-Push (push) Successful in 51s
Extends the tarpit protection and real IP handling to all backend templates, ensuring consistent behavior across different backend configurations. Changes to all backend templates: - Pass real client IP via X-CLIENT-IP and X-Real-IP headers - Use var(txn.real_ip) which contains the actual client IP (from proxy headers or direct) - Add scan attempt detection (400/401/403/404 errors) - Track suspicious paths (admin panels, config files, etc.) - Increment error counters for tarpit decisions Updated templates: - hap_backend.tpl: Main backend template - hap_backend_http_check.tpl: Backend with HTTP health checks - hap_backend_basic.tpl: Minimal backend configuration Benefits: - Backend applications receive the real client IP, not proxy IPs - All backend types now contribute to scan detection - Consistent security across different backend configurations - Works seamlessly with Cloudflare and other CDNs 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
