The code I create gets packaged, ready to deploy onto the test, stage, and production hosts. What I absolutely do not want to happen, and it’s happened recently, is for those packages to

Hosting multiple web servers behind a single IP address

Leave a Comment / FreeBSD, nginx, Open Source / By Dan Langille / November 15, 2020
