Setup & Best Practices for ServeTrue IQ Proxy (formerly Fastream IQ Proxy Server)
1) Quick preparation
- Platform: Windows server (supported Windows Server / desktop versions).
- Prereqs: Dedicated machine (multi-core CPU), enough RAM and disk for cache, static IP, firewall rules allowing proxy ports (default HTTP/HTTPS ports as configured).
- User account: Run service as a non-interactive, least-privileged account.
2) Installation & initial configuration
- Download installer from vendor/verified repository and run as administrator.
- Choose installation path on fast disk (SSD recommended for cache).
- Start service and open the admin console/web UI.
- Set listening interfaces and port(s) (bind only to required NICs).
- Configure SSL certificate for HTTPS (import a valid certificate for reverse-proxy; use CA-signed certs in production).
- Enable/verify cache engine and set cache storage location and size.
3) Reverse-proxy / load-balancing setup
- Add backend web servers with FQDN/IP and health-check endpoints.
- Enable smart failover and configure health check frequency and thresholds.
- Configure sticky sessions only if necessary (use cookie-based sticky when backend requires it).
- Use URL rewrite rules and routing rules to map incoming paths to backends.
4) Caching best practices
- Cache sizing: Allocate disk and RAM based on traffic (start conservative, monitor hit ratio).
- Cache rules: Honor origin Cache-Control/Expires headers by default; create URL rules for static content (images, JS, CSS) to force longer TTLs.
- Compression: Enable gzip/deflate for responses to save bandwidth.
- Purge policy: Configure safe purge/expiration procedures for deployments and content updates.
5) Security hardening
- Minimize exposed information: Remove or sanitize identifying headers (Server, X-Cache, Via) where supported.
- Restrict management access to admin UI by IP and TLS.
- TLS settings: Use strong ciphers, TLS 1.2+ only, and enable HSTS for reverse-proxy sites.
- Access controls: Apply ACLs to restrict who can use the forward-proxy and which backends are routable.
- HTTP method restrictions: Block unsafe/unused methods (PUT, DELETE) unless required.
- Run updates: Patch the OS and proxy software regularly.
- File permissions: Ensure config and certificate files are readable only by the service account.
6) Logging, monitoring & observability
- Detailed logging: Enable access and error logs; include cache hit/miss details.
- Log rotation: Configure rotation and retention to prevent disk exhaustion.
- Health metrics: Monitor connections, requests/sec, cache hit ratio, backend latency, and error rates.
- Alerts: Create alerts for high error rates, low cache hit ratio, or backend failures.
7) Performance tuning
- Connection limits: Tune max concurrent connections and keep-alive timeouts for expected load.
- Thread/worker tuning: Adjust worker/process counts to match CPU cores and memory.
- Timeouts: Set reasonable backend timeouts to avoid hung requests.
- Use RAM cache for hot objects if supported; fall back to disk cache for larger capacity.
8) Operational practices
- Staging before production: Test config changes in a staging environment.
- Rollback plan: Keep previous configs and a documented rollback procedure.
- Automated deployments: Use version-controlled config and scripted deployments.
- Change windows: Schedule cache-busting or certificate rotations during low-traffic windows.
9) Backup & recovery
- Config backups: Regularly export and store configs and SSL key material securely.
- Disaster recovery: Document steps to rebuild service on a new server (installation, certs, config import).
10) Common gotchas
- SSL offloading + backend HTTPS: ensure backend hostname verification/headers are correct.
- Incorrect cache rules causing stale content — use cache-control and purge strategies.
- Overly permissive ACLs exposing forward-proxy to abuse — lock down by source IP/auth.
If you want, I can provide:
- a sample reverse-proxy config for a basic site, or
- a checklist tailored to your Windows Server version and expected traffic (assume defaults otherwise).
