Unavailable Sites
The Internet and WWW are dynamic—they are always changing, and inherent in that
change is the fact that some Web sites may no longer exist or their addresses might
change. Web sites are consistently being updated as well. If you click a link, you might
encounter an error message. Two common messages that appear in dialog boxes are
“server busy” and “DNS entry not found.” Either of these messages means that your
browser was unable to communicate successfully with the Web server that stores the page
you requested. The cause of this inability might be temporary—in which case, you will be
able to use the hyperlink later—or the cause might be permanent, and the Web site or
Web page no longer exists. The browser has no way of determining the cause of the con-
nection failure, so it provides the same error messages in both cases. Another error mes-
sage that you might receive is displayed as a Web page and includes the text “File not
Found.” This error message usually means that the Web page’s location has changed per-
manently or that the Web page no longer exists.
As you continue to research information for Susan, you may not be able to remember
all the URLs of the sites you visit. The Back and Forward buttons only store URLs for a cur-
rent session, but what if you want to return to sites you visited two days ago? Internet
Explorer has a feature, the History list, that tracks sites visited for a specified period of
time, and you can access this information using the History Explorer bar.
Using the History List
You have used the Back and Forward buttons as a means for navigating through Web
pages viewed in your current browser session. Once you close the browser, the trail of
visited sites is lost. However, Internet Explorer provides another feature, the History list,
which tracks the Web sites that you have visited over a time period, not just during a
browsing session. The History list contains the URLs for the Web sites and pages that you
have visited. You click the History button on the Standard Buttons toolbar to open the
History Explorer bar, which displays the History list. To return to a particular page, click
that page’s entry in the list. You can see the full URL of any item in the History Explorer
bar by moving the mouse pointer over the History list item. The entries in the History
Explorer bar are listed in alphabetical order and not in the order in which you visited the
sites. You change the way in which the sites are listed by clicking View in the History
Explorer bar, and choosing to view By Date, By Site, By Most Visited, and By Order
Visited Today. You can also search the History list by clicking Search in the History
Explorer bar.
The History list displays not only sites visited today, but also sites visited yesterday, the
day before that, even last week, depending on the number of days specified in the Internet
Options dialog box. You open the Internet Options dialog box from the Tools menu.
(Changing Internet Explorer settings goes beyond the scope of this tutorial.)
To view the History list for this session:
1. Click the History button on the Standard Buttons toolbar to open the History Explorer bar
in the left pane of the Internet Explorer window. The History list stores each URL you have
visited today and for other specified time periods (for example, 2 Weeks Ago, 3 Weeks Ago,
and Last Week) in folders. It also maintains the hierarchy of each Web site; that is, pages
you visit at a particular Web site are stored in a separate folder for that site. You can right-
click any entry in the History list and copy the URL or delete it from the list. Internet
Explorer stores each entry in the History list as a shortcut in the History folder, which is in
the Windows folder.
