Web browsers cache HTML files, JavaScript, CSS, images to speed up the website which is a vital factor for Search Engine Optimization (SEO). 2. 404 Error Not Found A 404 Error message is an HTTP status code giving the information to the user that the server was unable to find the requested website/webpage. HTTP ” 404 Not Found ” client error reply code indicates that the client’s requested web page does not exist on the server. A 404 status code does not indicate whether the resource is temporarily or permanently missing. Customize 404 page is more helpful to the visitor and provides information on what to do next.
