Free MySQL Load Balancing PHP script. For load balanced access to your MySQL servers when you are using MySQL replication between one (or many) master and many slaves. This script does reads on slaves and writes on master(s). It automatically checks if the challenger slave is "fresh enough" to read on it. The script is actually used in real conditions, prove of the capabilities. That also needed from me to erase some sections of the code replaced by a "TODO" commentary with instruction (you will have to adapt those few lines to your conditions). Comes with a mail alert script for errors logging and reporting, really useful for debug issues. Renaud CAMPO

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.

Zebra_Session is a PHP class that acts as a wrapper for PHP's default session handling functions but instead of storing session data in flat files it stores them in a MySQL database, thus providing both better security and better performance. The library is also a solution for applications that are scaled across multiple web servers (using a load balancer or a round-robin DNS) and where the user's session data needs to be available. Storing sessions in a database makes them available to all of the servers! Zebra_Session's code is heavily commented and generates no warnings/errors/notices when PHP's error reporting level is set to E_ALL. Starting with version 2.0, Zebra_Session implements row locks, ensuring that data is correctly handled in a scenario with multiple concurrent AJAX requests.
