The Ultimate Nginx Guide: How to Elegantly Redirect Multi-Domain HTTP/HTTPS Traffic to a Single Subdomain

This article provides an in-depth guide on how to efficiently use Nginx to 301 redirect all HTTP and HTTPS requests from multiple domains (e.g., example.com and www.example.com) to a single target subdomain (e.g., dpit.lib00.com). Starting with a basic two-server-block configuration, we progressively optimize it into a cleaner, more professional single-server-block solution. The guide also addresses common questions about performance impact and industry best practices for logging. This is a must-read for both Nginx beginners and experienced developers looking to refine their configurations.
