Internet history is handled by whichever browser you are using, therefor, the answer depends on that. I'll just answer the question for the two most common browsers. If you are using a different browser, you'll need to ask for that browser in particular. For Safari, under the "Safari" application menu, select "Reset Safari..." This will display a dialog with a list of history items (e.g. cache, cookies, etc.). Select or deselect whichever options are appropriate. For Firefox, go to "Preferences" by clicking on the apple icon in the top left corner. Click on the "Privacy" category and click the button "Clear Now..." under "Private Data". Select and deselect as necessary.
