CACHE AND
COOKIES
|
|
There are times when
you're going to want to clear your browser's cache and your temp files. If
you have a utility program, this may be done for you automatically on al
regular basis.
What is " cache"?
Think of cache as storage. Your browser automatically saves images and
web pages that you visit so that the next time you visit them, the page
loads a lot faster. The advantages out weigh the problems but here
are two concerns. Sometimes a page won't load properly or you
get the "old version". Also, all of these files take
up loads of room on your hard drive.
How do I remove them myself?
There are some fancy ways you can do this by going directly into your
browser and looking at your options and preferences. Here is
another way. Go to your start menu and click on find and select
files or folders. Type in cache into the first line for location
and click Find Now. There will be a lot. If you use Netscape
look for a file folder that is probably listed as C:\\Program Files/Netscape/Users.
For Outlook you need to search for temp files. Look for C:\WINDOWS\Temporary Internet Files.
Click on folder and
when it opens go to Edit. Pick select all which will highlight
all the files and then go back to File and click delete.
Don't worry this is just fine to do.
Cookies Anyone? by
Mike Banks Valentine
There is one particular issue that relates specifically to the web and
your surfing, buying and e-mailing habits. You should know by now that
every site you visit can place a "cookie" on your hard drive
which will record a few crumbs of information about you.
This is harmless enough at first glance when all they seem to care about
is the time, date, length of stay and pages you visited at their site.
But when you know that advertisers that serve ads from the sites you
visit can also track your visit, link it to other stored data about you
gathered at other sites
and finally to any other information they have stored about you, how do
you feel?
This means that the harmless little "session number" or
"state data" gathered about you from every site you've ever
visited, every product you've ever purchased online and every banner
you've ever clicked on is stored in the database of the ad server and
distributed to it's clients!
To learn how to disable
cookies on your computer, click the link
Information provided by the largest cookie bakery on the web, DoubleClick.
It is possible to set your browser to the "Do Not Accept Any
Cookies" option. I recommend you try it once, if only for the
enlightenment about how many sources are collecting information about
you. Some web pages will send as many as a dozen requests for cookies
and many web sites tell you flatly that in order to use their online
service "cookies must be enabled on your browser" to use the
site.
It gets tiring and frustrating clicking the "OK" button in the
warning box that appears each time your browser detects a request to set
a cookie on your hard drive, if you've checked the "notify me"
option in preferences.
If you want to get a clearer picture of how cookies can be used to
invade your privacy, I recommend an amazing demonstration of how you can
be followed around the web without your knowledge. Privacy.net
has set up a demo at:
< http://www.privacy.net/track/
>
You'll see how providing information in bits and pieces to multiple web
sites creates a cumulative database on your travels, habits and
preferences online. Prepare to be mildly miffed or fully outraged,
depending on your level of concern with invasion of privacy.
It is becoming increasingly complex to keep your private information to
yourself. The biggest advertisers online have created a method which
involves cookies which stop new cookies. You must get yourself a set of
"No Cookies For Me" cookies from a group set up by this online
advertising brain trust. Now ya gotta have a new cookie to avoid getting
any more cookies.
No really, I couldn't eat another bite, please! If you'd like to follow
this recipe for avoiding advertiser spying on your surfing
habits, visit the Network Advertising Initiative web site and go to the
< http://www.networkadvertising.org/optout_nonppii.asp
> OPT OUT page, which gives you the option to tick boxes to opt out
of cookies served by the largest six online ad servers,
- DoubleClick
- Engage
- 24/7 Media
- Matchlogic
- Avenue A
- L90 Inc.
OK, now you're outta there, right? No, not necessarily. You've opted
out, but you use your wifes' computer or you use a different browser to
visit sites that serve the cookies you don't want, so you have to visit
the OPT OUT page again and check off those boxes for every computer and
every browser you use. This could get a bit tedious!
Most surfers don't know that the browser launched by their service
provider might be different from the built-in browser launched by their
operating system on start-up by the system. The ISP provided browser is
yet another version. Which one are you using now and on which computer
and did you visit the OPT OUT page with this one?
Fortunately, the NAI has set up a way for you to tell by going to the
verification page, which looks for those opt-out cookies and verifies
that you have them for each of the participating ad networks.
If you don't, you can go back to the OPT OUT page and get new OPT OUT
cookies. If that still doesn't work, you can go complain to someone set
up to police the activity of these cookie monsters. Guess who arranged
for this compliance service? Those same advertisers. HMMMM. Well it's
better than nothing. Just visit the Arthur
Anderson site.
Now you've filed a complaint and you can feel all better about it right?
Well only if they get a volume of complaints that suggests a
"significant" problem has occurred based on the number of
complaints filed, then they'll conduct an investigation. Man that's a
relief! I wonder if those ad networks will keep paying these guys to
tell them when they've gotten a significant number of complaints? I
wonder how much they pay for this service and who monitors the people
they are paying to tell them what they'd like to hear? They'd probably
stop paying me if I played this role, because I'd be telling
them every time a single complaint was lodged.
No thank you, I couldn't eat another bite!
