What is the purpose of caching what is viewed on the web? As mentioned on the previous page, caching can allow a browser to avoid reloading a page that has already been visited. Let's consider an example. Say that Mary launches Netscape and goes to usatoday.com to view the day's news. She then goes on to view some other sites - her best friend's personal home page, a Macintosh news page, etc. Mary then uses Netscape's Go menu to return to usatoday.com. Because the data for this page has been cached, it will load very quickly; Netscape does not need to download the text and graphics from the Internet the second time. Mary quits Netscape and goes to bed. The next morning she launches Netscape again and goes to usatoday.com. Netscape loads text and graphics that have not changed from the disk cache, which is usually faster than loading them from the Internet. In this case, only the USA Today logo is unchanged; all other text and images have been updated to reflect today's news. |
