Setting Cache and
Page Refresh
For faster performance, most web browsers cache web pages. If a page is
cached, an image of the web page is stored locally. When you navigate to
a page that has already been viewed, the browser will load the page from its
cache rather than loading it from the network.
Usually, this process works well for static web pages. However, this process
may cause problems for 'dynamically' changing web pages. This problem
may occur when you are navigating using the browser’s forward/back/
refresh options.
Doing this usually causes the browser to first look in its cache to see if the
page exists. If the page is cached, the browser displays the page from the
cache instead of going to the network to update changes. Since instrument
web pages are dynamic in nature, the cache may contain content that is
outdated. If you see a problem where dynamic pages are not being updated
automatically, the browser should be instructed to check for newer versions
of a web page on every page visit.
