What is the ngx_http_addition_module?
The ngx_http_addition_module in Nginx allows you to append HTML content during the processing of HTTP requests to the pages. This module works well for adding HTML code at specific locations in pages, especially when you need to display specific content before the body of the page is loaded.
By using this module, you can easily insert content into various sections of a web page. For example, you can place banners or advertisements before the main body's page load, which may help attract users or display specific information to them.
The method of using this module in the Nginx configuration file is relatively simple. You only need to add a directive to the Nginx configuration file itself and specify a path for the file you want to add as supplementary content. With this, you can easily add HTML content.
Before using this module, you must ensure that Nginx is compiled with this module. After that, you can proceed to add the necessary directives for including the content.
