Thanks to the cache stored by the browser, we do not need to reload pages every time we visit them, since they are saved on our computer’s hard drive. This speeds up browsing, especially if we visit the same page multiple times.
Sometimes, we will need to clear the browser cache in order to view certain changes on the page we want to visit. Before clearing the browser cache, we can try reloading the page without using the cache by pressing Ctrl+F5.
If it still does not load correctly, we can clear the browser cache along with the DNS resolution cache. Below we explain how to clear the cache in the main browsers:
1.-Google Chrome
1. In the top right corner, click on More

.
2. Click on More tools

and then Clear browsing data.
3. At the top, choose a time range. To delete everything, select All time.
4. Check the boxes next to "Cookies and other site data" and "Cached images and files".
5. Click Clear data.
2.-Mozilla Firefox
1. Click on the menu button and select Settings.
2. Select the Privacy & Security panel.
3. In the Cookies and Site Data section, click Clear Data…
4. Uncheck the box next to Cookies and Site Data.
5. Once you have checked the Cached Web Content box, click Clear.
6. Close the about:preferences page. Any changes you made will be saved automatically.
3.-Internet Explorer
1. Click on the Settings icon in the top right corner to open the Tools menu.
2. Select "Safety > Delete Browsing History".

OPERATING SYSTEMS
1.-Windows
Click on "Start".
Click "Run" and type the command "cmd" (without quotes).
Click "OK".
In the command console type "ipconfig /flushdns".
If the command has been executed correctly, the following message should appear: "Successfully flushed the DNS Resolver Cache."
2.-Mac
The command to run in a terminal is "lookupd -flushcache".
In newer versions (Leopard), you may need to use "dscacheutil -flushcache".
3.-Linux
In Linux, to clear the DNS resolution cache you must restart the "nscd" daemon. To do this, use the command "/etc/init.d/nscd restart" in an SSH terminal.
