+## Enable njs module
+
+The original URL are case-sensitive and we'd like to normalize it as lowercase. For that we can use the njs module to allow us to compute with javascript.
+
+Edit the nginx.conf file and load the module outside the http block.
+
+```sh
+load_module modules/ngx_http_js_module.so;
+
+http {
+  ...
+}
+```
+
+Include the path where the njs script is going to be located, import the script and set the utility variable.
+
+```sh
+js_path "/etc/nginx/njs/";
+js_import utils from lowercase.js;
+js_set $lc utils.lowercase;
+```
+
+Create the directory njs
+
+```sh
+mkdir /etc/nginx/njs
+```
+
+Create the script file
+
+```sh
+touch /etc/nginx/njs/lowercase.js
+```
+
+Open the file and put the content
+
+```sh
+function lowercase(r) {
+    var originalValue = r.uri.split(/^\/(docs|post)(.*)$/)[2];
+    var lowercased = originalValue.toLowerCase();
+    return lowercased;
+}
+```

 ## Usage
