Open Source PHP Reverse Proxy Servers

Setting a trusted proxy allows for correct URL generation, redirecting, session handling and logging in Laravel when behind a reverse proxy such as a load balancer or cache. Laravel 5.5+ comes with this package. If you are using Laravel 5.5 or greater, you do not need to add this to your project separately. Setting a trusted proxy allows for correct URL generation, redirecting, session handling and logging in Laravel when behind a reverse proxy. This is useful if your web servers sit behind a load balancer (Nginx, HAProxy, Envoy, ELB/ALB, etc), HTTP cache (CloudFlare, Squid, Varnish, etc), or other intermediary (reverse) proxy. Laravel (technically the Symfony HTTP base classes) have a concept of a "trusted proxy", where those X-Forwarded headers will only be used if the source IP address of the request is known. In other words, it only trusts those headers if the proxy is trusted.
