title: Difference between F5, Ctrl + F5 and click on refresh button?
body: <p>I have often experienced while developing my web applications that pressing <kbd>F5</kbd> or refresh doesn't produce or refresh the proper result. But when we hit <kbd>Ctrl</kbd> + <kbd>F5</kbd> it generates the correct result. What is the basic difference between simple <kbd>F5</kbd> and <kbd>Ctrl</kbd> + <kbd>F5</kbd>?</p>
  <p>I have often also experienced that pressing simple <kbd>F5</kbd> and pressing the <kbd>Refresh</kbd> button in the browser also generate different results.</p>
  <p>What is the basic difference among all these requests?</p>
