NGINX WordPress Rewrites

After moving my blog to its new domain try-catch-finally.net there was one major issue open: Search engines. Google, Bing, DucDuckGo and whatever have their indices. Eventually, I want to make sure when you hit one of the search results, you will end up with the proper site.

Using NGINX allows you to do this with a few files. Using the location section let you match against path segments and applying a rewrite rule.

The trick is done by the two parameters $1 and $1. While the $1 is the content in the first paratheses, $2 is the rest of the path segment from your request which is in the second paratheses. Once I got this pattern, It was easy to write the below rule.

server {   
  ...   
  location location ~ /(2004|2005|2006|2007|2008|2009|2010|2011|2012|2013|2014|2018|2019|feed|comments|tag|author|category)/(.*) {
    return 301 https://try-catch-finally.net/$1/$2;     
  }   
  ... 
}

In addition to just forwarding your request, the client will receive the HTTP status code 301, that way there is a good chance search engines get the information about the change for this particular URL.
