Ctrl + F5

It was the first day of our new employee 'the girl who resides by the office'. She was trying to view one of our dev web page. Some of the features where not getting loaded. She asked 'the Senior and Tall person' sitting beside, what to do. He said, 'Refresh' the page. She asked 'How?'. He replied 'Press Ctrl+F5'. She did something and said 'Its not working'. Senior told her 'Try again'. This time Senior was looking what she was doing. Senior burst into laughter at what she did.. Soon the whole of office knew what she did and where laughing. you people also want to know what she did? She pressed 'Ctrl + F + i'
