Actually I think your question has to go a little bit further? But I will try to answer as best as can be answered. You can on most browsers delete files associated with traveling on the internet. As an example in Internet Explorer. You would do the following:
1. Go to "Tools".
2. Click on "Internet Options...".
3. Then click on the "Delete Cookies..." button.
4. Then click on the "Delete Files..." button.
5. Then click on the "OK" button to exit.
