Browsers are really good at caching your data. Most time this is exactly what you need until you are building a Single Page Applications and continuously are changing the used HTML,CSS and JavaScript files.
To simplify the debugging process you can (temporarily) disable the browser cache:
- In Internet Explorer:
- Open the Developer Tools(F12)
- Go to the Cache menu item and enable the Always refresh from server option.
- In Chrome:
- Open the Developer Tools(F12)
- Go to the Settings by clicking on the small icon in the right corner:
- On the Settings page check the checkbox next to Disable cache(while DevTools is open).
- In FireFox:
- Open FireBug(F12)
- Go the Net menu item and click on the small arrow next to it. Select the Disable Browser Cache option.
