When you use your
browser to visit a website, you would generally get the latest
content available on that website. If you again visit the same
web page or website, then you would expect the updated content
to be displayed in the browser. Normally, the updated content on
the same web page will be automatically displayed in the browser
on your next visit to the same web page. But sometimes, you may
notice that your browser does not show the updated contents of a
web page or the website, and instead it continues to display the
old contents. Even refreshing the page won’t help. How to
rectify this problem?
In fact, when you
browse the Internet, and view web pages, the files, images,
pictures, sound, cookies, etc., associated with those web pages
are stored by your browser on your computer in what is known as
“cache” or “browser cache” (cache is nothing but the
folder that stores temporary Internet files). This is done to
speed up the display of web pages that you frequently visit
since the next time you visit the same web page, the browser can
open them from your computer instead of downloading those files,
images, etc., again from the web. In fact, there are many parts
of a web page that generally do not change or they change after
considerable time. For example, the logo of a website would
normally not change for months or may be years. Therefore, the
browser will store the logo image on your computer. Next time
when you visit the same web page or web site, the browser does
not have to download the same logo again and it can use the logo
already saved on your computer. It makes your browsing faster
and moreover, it also saves your bandwidth. This is done by all
browsers, including Internet Explorer, Mozilla Firefox, Google
Chrome, Safari, Opera, etc.
When the content
on a web page is updated, the next time you visit the same web
page, the browser comes to know that a newer version of the web
page or an image or logo or sound file, etc., is available (by
comparing the file versions); and, accordingly, the browser
downloads the updated content from the web page, instead of
using the stored content on your computer / laptop in the cache.
Therefore, usually your browser will display the updated
contents on your subsequent visits to a web page. However,
sometimes, it does not happen. Even if you try to refresh the
page, the browser still shows the same old content. This may be
due to some problem in settings; your settings may not be
correct, or cache might have got corrupted or there may even be
some virus / malware trying to interfere with your browser
working.
Let’s see how we
can ensure that the web page is updated automatically as and
when new content is available on it during your subsequent
visits to it.
(A)
Adjusting how often to update content from the web (change
settings):
Do you want faster
browser speed by loading files stored in cache of browser during
previous visits to a web page, or, you want to get updated
content every time since a web page might have changed after
your last visit to it? In some browsers, you can customize how
often the browser checks the web for updated contents on the
pages visited by you. Internet Explorer gives you the full
freedom to customize this option in an easy user-friendly
manner. Firefox has the feature to customize this option, but it
is not user-friendly and is hidden deep inside the configuration
settings which you cannot edit unless you know where those
settings are and you’ve some expertise doing it (I’ll be
discussing the topic – how to change these configuration
settings in Firefox – in a separate article, later). Google
Chrome has no such customization settings at all.
Let’s see how to
change the auto-update settings in Internet Explorer:
(1) Open Internet
Explorer. On the Tools menu, click
Internet Options. Or alternatively, on the
toolbar, click on Tools button and from the
drop-down menu, select Internet Options.
The
Internet Options dialog box will open. Display the
General tab, if it is not displayed already.
(2) If you’ve IE
6, on the General tab, in the Temporary
Internet Files section, click the Settings
button. This will open the Settings box.
If you’ve the
latest version such as IE 8, in the Browsing history
section, click Settings button. This
will open the Temporary Internet Files and History
Settings box, as shown below:

Now, in these
settings, you’ll notice four different ways to check for newer /
updated contents of web pages from the Internet that were
earlier stored in the cache or the Temporary Internet Files
folder. These are explained as under:
-
Every
time I visit the web page: If you select this
option, you’re assured of the most current
content from the websites, but it’ll be slower since the
browser will be downloading the content every time from the
Internet even if the same files are already stored in its
cache.
-
Every
time I start Internet Explorer: If you select this
option, on your first visit to a web page after you start
Internet Explorer, it will check for new information or
updated content from a web page, but it will not do so on
your subsequent visits to the same web page in the
same browsing session.
-
Automatically: With this option set, the Internet
Explorer will automatically check for any new content. That
means it will compare the stored files with the files found
on Internet during the next visit; and, if any newer version
of the same file is found (say, the image files), it will
automatically download it; but if no new version of the same
file is found on the web, it will use the file stored in the
cache. This is generally the best and the optimized option
since it ensures faster browsing, and at the same time you
get updated content whenever available.
-
Never:
This option means the fastest browsing (and it saves your
bandwidth too) since the IE will never check for updated
contents during your next visits to the same web page, but
the downside is that you could be viewing old content from
the cache of your computer. This option is suitable when you
know that the websites mostly visited by you rarely change
and have mostly static content. However, even with this
option selected, it is possible to get the updated content.
To refresh the displayed web page and to get the updated
content, press the F5 key on your keyboard;
this will download updated content from that web page and
store it in your cache.
So, accordingly,
you can select the option best suited to you for getting updated
contents from the web.
(B)
Refresh / Reload the web page by using F5 key or Ctrl + F5 keys:
If in spite of
having proper settings for updating contents, you’re getting old
information from the web page, you can manually refresh the web
page.
For refreshing the
currently displayed web page in your browser, press the
F5 key or click on the Refresh / Reload
button in your browser (in Firefox and Chrome, additionally
you can also use Ctrl
+ R keys together for this action). This will
make the browser to check for updated contents from the web page
and download the same. So, any new information / updated content
will be downloaded from the web.
If even pressing
the F5 key or clicking on the Refresh /
Reload button does not show the updated content, then
you can try pressing Ctrl + F5 keys together
(in Firefox, you can also use
Ctrl + Shift + R keys
together for this action; likewise, in Chrome, you can
also use Shift + F5
keys together for this action). This will refresh the
current webpage contents, even if the time stamp for the web
version and your locally stored version in the cache are the
same. Thus, this action will reload your current page, ignoring
the contents stored in the cache. Or, you can say that your
cache options are overridden with this action and a refresh or
reload of the web page is forced.
(C) Clear
the Cache of your browser:
To force updated
contents being downloaded from the web instead of using the
cache contents on your computer, you can clear the contents of
the browser cache. This means that all the stored or downloaded
files from various web pages will be deleted or cleared from the
cache or the Temporary Internet Files folder. Moreover, clearing
the cache also resets its index. All browsers give the options
to easily clear the cache on your computer.
(D) Check
for virus / spyware affecting your browser operations:
Sometimes, it
may be possible that a virus / malware is interfering with
your browser working that may be forcing it not to update
contents from the web pages. So, try checking for malware or
virus on your computer using some good anti-virus and/or
anti-malware software.
Conclusion:
Generally
speaking, using the aforesaid methods should solve the problem
that the contents of the web pages are not updated when you
visit those web pages again.
