The browser cache provides local storage of files previously accessed and downloaded from a web server. Faster Loading. Because files are stored locally, previously viewed pages load faster, as long as they are stored in cache. Reduces Network Congestion. Every time you access a web site, you are downloading files.
The basic Cache-Control header defines amount of time that a file should be cached and the manner in which that caching should take place. When a file is accessed by a browser the HTTP headers are also retrieved. When the Cache-Control header is included the browser will respect the values found there. If a browser sees that a file should be cached for five minutes, it will stay in the browser cache for five minutes and that file will not have to be retrieved if it is called again. An example might be your logo image.
