Have You Ever Wondered About Cookies?

Do you remember the first time you was offered a cookie 
from a web site? If you were new to the Internet it was a 
surprise. A web site wanted to put a cookie on your 
computer.

Maybe your first thoughts were, "What's a cookie? Should I 
accept it or reject it?"

Some sites never asked to give you a cookie... Other sites 
required your acceptance of cookies to get information, to 
read articles or look through their products or get their free 
downloads.

According to Netscape, "Cookies are a general mechanism 
which server side connections (such as CGI scripts) can 
use to both store and retrieve information on the client side 
of the connection."

Most cookies are set once and then go away when you turn 
off your browser. The other type of cookie, the persistent 
cookie, is set and remains on your hard drive until either 
your space for cookies is full or the time stamp on it expires.

A site has access to any information you provide (including 
information like your IP address, browser type, and the page 
that referred you to their site, as well as forms you fill out) 
without using any cookies at all. So, it's more important to 
know the privacy policies of a site than to worry about 
whether they use cookies.

Cookies are small pieces of information gathered from you 
and/or your computer by a web server and stored in your 
computer, ready for future access by the server or web site. 
Cookies are embedded in the HTML information flowing 
back and forth between your computer and the web sites 
and servers.

What's The Purpose of Cookies? They allow user side 
customization of web information. For example, cookies are 
used to personalize web sites. They allow you to participate 
in surveys, contests... And, making sure you participate only 
once... And to store shopping lists of items you have 
selected while browsing through a list of products or a 
virtual shopping mall.

Some sites require YOU accept cookies to access their 
information, tips or articles from their web site. Cookies 
make use of specific information you prefer. That specific 
information is transmitted by your web server into your 
computer cookie file so the information is available for later 
access by itself and other servers.

In most cases, not only does the storage of personal 
information into your cookie file go unnoticed, so does 
access to it. Web servers automatically gain access to 
relevant cookies whenever you establish a connection to 
them.

Cookies are based on a two-stage process. First, the 
cookie is stored in your computer sometimes without your 
consent or knowledge. But... On Netscape browsers you 
can go to preferences, set your browser to alert you before 
accepting a cookie. On Internet Explorer follow the 
Tools/Internet Options/Security menu to set cookie 
preferences. It's your choice.

For example... Some web pages are customizable so you 
can select categories of interest to you from the web page. 
The web server then creates a cookie that is a string of text 
containing your preferences, and puts this small cookie text 
file in your computer.

If your web browser is set to receive cookies... the cookie 
text is stored on your computer in a file called a cookie file. 
This happens without your consent unless your have set 
your browser to notify you before accepting a cookie and 
before it is stored on your computer.

Would you like to see your cookie file?

On a Macintosh you can do a find for 'magiccookie' on your 
hard drive...

On a PC do a find for 'cookies.txt' on your hard drive.

Each cookie file is a small text file. After you find the file you 
can open it by double clicking it. Looking at the files doesn't 
tell you much unless you get deeper into writing and setting 
cookies.

Remember... a site only knows what information you've 
entered and your browser type and ISP. Cookies are neither 
good nor bad, they can provide convenience for you and do 
serve useful functions on the web.

You CAN delete the entire cookies file on your computer if 
cookies concern you. Just find the file and delete it. Then set 
your browser preferences to NOT accept cookies.

"I've always accepted cookies and have noticed no bad 
effects. So my personal preference is to continue accepting 
them,"... Now It's Your Choice!
