It is popular for creating powerful web applications and sites, as well as for powering popular web applications like WordPress.

What is a 404 Not Found Error?

The 404 Not Found Error is an error code that is returned when a web server is unable to find the page, file, or resource that is requested by the browser. This is usually caused when a website or web server has moved or been removed. The error message typically states that the requested resource is not found on the server, and it suggests an alternative. It also includes the HTTP status code, which is an indicator of the error.

What is an Nginx Reverse Proxy?

An Nginx reverse proxy is a server that sits between web clients and web servers. It offers a number of advantages over traditional proxy solutions that include improved scalability, higher performance, better security, and flexibility. Nginx reverse proxy servers are used to handle requests from browsers sent to web servers in a secure manner. The Nginx reverse proxy server handles incoming requests from browsers, and forwards them to web servers for responses.

How Does Nginx Reverse Proxy Work With CodeIgniter?

An Nginx reverse proxy is a great way to improve the performance of CodeIgniter applications on the web. The Nginx reverse proxy server will handle incoming requests from web browsers while allowing the CodeIgniter application to continue to serve them. It will also help to improve the security of the application by hiding the web server from potential attackers. In addition, the Nginx reverse proxy can help to improve scalability and performance by acting as a load balancer between web servers.
