Caching a dynamic page can effectively create a static HTML file of that page. When you cache a dynamic page, the server generates and stores a static HTML version of that page. This cached version is then served to visitors, reducing the need for server-side processing and database queries, which results in faster page load times and reduced server load.
It's important to note that caching a dynamic page does not permanently convert it into a static HTML file. The dynamic aspects of the page still exist, but the caching mechanism helps improve performance by serving a static version to visitors whenever possible.
