Introduction
Greetings, readers! In today’s digital age, securing your website with HTTPS has never been more crucial. With HTTPS, you not only protect user data, but you also improve your website’s search engine optimization (SEO). However, managing multiple server names with HTTPS can be a challenge. This is where Nginx comes in. In this article, we’ll take a closer look at Nginx multiple server names HTTPS and how it can benefit your website.
What is Nginx?
Nginx (pronounced “engine-x”) is an open-source web server software that’s known for its high performance and low memory usage.
