Meta refresh is a method of instructing a web browser to automatically refresh the current web page or frame after a given time interval, using an HTML meta element with the http-equiv parameter set to "refresh" and a content parameter giving the time interval in seconds.

Occasionally this caching scheme goes awry (e.g. the browser insists on showing out-of-date content) making it necessary to bypass the cache, thus forcing your browser to re-download a web page's complete, up-to-date content. This is sometimes referred to as a "hard refresh", "cache refresh", or "uncached reload".
If you've cleared the cache in your web browser, but are still experiencing issues, you may need to restore its original settings.This can remove adware, get rid of extensions you didn't install, and improve overall performance.
