How to Clear History, Cookies and Cache on the Safari Web Browser for the IPhone
Safari is the default Internet Browser on the iPhone. Since it is a full browser, sometimes the most visited websites will act sluggish. Normally, the first suggestion a person receives it to clear the cache and cookies on the browser. In addition to clearing the cache and the cookie files, a person may need to clear the history information. The history file stores a link to all the previously visited websites using the Safari browser. Clearing this information is fairly easy and quick on the iPhone.
Locate the "Settings" button and press it.
Select "Safari" from the menu.
Scroll down until "Clear History" appears on the Screen. Select it. A confirmation message will appear on the screen.
Select "Clear History." This will bring you back to the Safari menu.
Select "Clear Cookies." Once again, a confirmation screen will appear. Select "Clear Cookies." You are now on the Safari menu screen again.
Select "Clear Cache." Once the confirmation screen loads, select "Clear Cache" again. At this point, the clearing process is complete.
