How To Clear Browser Cache

In our WordPress website there are the following types of cache:#

  • Browser Cache – Browser cache is a temporary storage location in our computer in which recently used information files are downloaded by our browser to show the websites faster. It is very important to save data and storing it for later use, cache file that are cache locally contain all the essential file that makes up the websites, such as HTML, CSS style sheet, JavaScript scripts, PHP scripts, graphics images and multimedia content.
  • Cache Plugin – A cache plugin use specifically to speed up our web pages loading time, it basically creates static version of our website. Caching causes a problem when we make changes in our website and it’s not shown the changes in front end, because it shows the cache data in that case we have to clear data from our cache plugin, and we have keep it disable until we have finished changes in our website.
  • Server Cache – A server cache store on local network temporarily to recently requested information from the internet, it helps to speed up to load data and reduce the uses of an enterprise’s bandwidth.
