Web page caching

Many commercial and noncommercial products come with caching options. Inspect your applications and evaluate whether you need to use caching. If you are developing a new application or are using an existing application that does not have a caching capability, you can implement one yourself with very little programming. There are many ways to accomplish web caching. In this subsection, I will explain how to implement one of the simplest wed caching techniques. It involves obtaining a particular dynamic web page snapshot in time and then serving this static version to end users. Furthermore, to ensure content freshness, there is usually a scheduled, automated task that repeats the process at defined intervals. The most popular use of web application caching is for news websites. Making his work well requires knowing and using the so-called welcome files in the right order. You can think of welcome files as default web page files that will open if a web user requests a URL, only specifying a directory at the end of the URL. The web server than looks at the welcome file list to determine what to serve. Usually, on PHP host the first file to be served is index. html or index .htm. This is followed by index.php.
