Frequently asked questions
Why choose HAProxy over another proxy?
HAProxy is renowned for its extreme speed and reliability. Unlike Nginx, which is a versatile web server, HAProxy is a pure load balancing specialist with much finer health check and persistence features.
Does HAProxy handle HTTPS traffic?
Yes, perfectly. It can either do 'SSL Pass-through' (letting the backend decrypt) or 'SSL Termination' (HAProxy decrypts and offloads the web servers).
What is an ACL in HAProxy?
An ACL (Access Control List) lets you make intelligent routing decisions based on criteria such as the URL, the source IP address or HTTP headers.
