Ensuring Real-Time Progress Updates with AJAX for CGI Scripts

In web development, real-time progress updates during file uploads can significantly enhance the user experience. Ensuring your AJAX request fetches real-time progress updates from your CGI script involves several key steps. This guide will guide you through the process, focusing on using JavaScript, C, and AJAX.
