Nginx server blocks processing order of priority

In the previous post Multiple ways to test a Nginx location match I wrote about how to test the location match but here’s the thing. You need to know the order first before testing anything, right?!

Prerequisites

• Nginx

Solution

The processing order of priority when dealing with Nginx server blocks is the following one:

1. The exact names being processed first.
2. Longest wildcard names starting with an asterisk * e.g. *.devcoops.com.
3. Longest wildcard names ending with an asterisk * e.g. preprod.*.
4. First matching regular expression (in order of appearance in a config file).
5. The default server block.
