||Q. Can cookies be used to get a "snap shot" of my hard drive? Is this done? and how?
Q. Can someone from one site access the cookie information written by another site?
A site can only access a cookie that has been set from its own domain, It cannot access any other cookies from your computer. Sites could access other site's cookies, again this problem was plugged a long time ago.
Q. Is there a way to see the cookies that a web site has set?
Are there other means of tracking web surfers than cookies?
There is many ways in which you are traced on the web; cookies are seen more like a personal tag, some people see then as the most invasive of privacy. They are the only tracking device that we can control. Every time you log on to a web site you give away a lot of information:
- Service provider.
- Operating System.
- Browser type.
- Screen resolution and amount of colors. (only in IE)
- CPU type.
- Your service provider's proxy server (if used).
- You IP address (again, this changes)
- What server you were on last
You can stop this information from being given away by going to Anonymizer ; this site works like a proxy server, which also filters cookies.
Q. Are cookies a from big brother the same as ones in a online shop?
A. Well there is a bit of both, the function of the cookie is the same but they can be implemented in different ways. Cookies can be used to store information about where you go, and what banners you click, so companies can put specialized Advertisements and data which appeal to you. It's a bit like someone putting a tag on you when you go into a supermarket and then following you around the store. Some folk consider this loss of privacy offensive. But also they can be used for innocent things like storing what you have brought in an online shop, by assigning an ID number in a cookie. But whatever they are used for, they are the same thing. They are a valuable function on the web, for accomplishing a number of things.
Q. I use Internet Explorer 3 and have 2 cookies -- MM2048, MM256. They arrived before I discovered the warning message. I got rid of other cookies but I am not able to delete these. I get an error message when I try to delete them. Any suggestions? I use Windows 95.
A. These are not cookies. They are part of the IE 3.0 browser cache. I myself do not allow cookies to be stored, but I also have mm2048.dat and mm256.dat. They are nothing which you have to concern yourself. I do not know why part of the cache is in the windows/cookies directory.
Client UrlCache MMF Ver 3.2
It found a lot of stuff (summarizing my cookies??) in mm256.dat. For your information, I am including the cookie sent by doubleclick, and the list of strings I found in mm256.dat. The top doubleclick cookie is the last one I received. The others are other experiments.
Here are what strings was reported on mm256.dat:
Client UrlCache MMF Ver 3.2 w"f2
Q. I set my browser to alert me before accepting cookies. In the dialog box in which the cookie offer is made, there is always the implicit threat that if you do not take the offer, you will not be able to enjoy the site you are visiting as well as you anticipate?
A. While not accepting a cookie will probably not reduce the experience of the site, obviously if you go into a online shop and reject a cookie you cannot shop properly. It is possible for a site to not operate properly if cookies are not accepted. I do not know how many fall into this category right now. Cookies was firstly developed by Netscape and now implemented by the RFC, so they want cookies to be used, the message box is just telling you that the site you are entering may not function properly if you do not accept the cookie, most sites work fine if you decline a cookie. It's is the persons opinion whether to accept cookies or not, Most people do not set their browser to warn them before accepting cookies because it becomes really annoying when a site wants to set 10 cookies. It would be quite easy for Netscape or Microsoft just to decline cookies automatically but this may render them useless. I work on the theory that there is less harm declining them than accepting them, this works for me. Please note the final version of Netscape Communicator and the betas, has options to automatically reject cookies.
Q. What Use Is The Information We Reveal To Web Sites?
A. The information that people reveal to each Web site they visit can be used by system administrators to build extensive personal profiles of visitors. By automatically placing a Cookie on visitors' Web browsers, Servers register data on the Cookie. This allows administrators to view the history of site's users has last visited before they enter that site, the advertisements they have viewed and the online transactions they have conducted. Again, sites can only access cookies from their own domain. While Cookies can be useful in some situations (for example, in saving a user's password to a particular site), some people constitute this as invasion of privacy. Remember a web site only knows the data that you have entered.
Q. Why Do Some People Dislike Cookies?
A. Cookies are sometimes disliked because they can set and perform functions without the user knowing. But couldn't one view computers in general as setting and performing functions without the user knowing? My machine swaps programs in and out every few seconds without telling me about it. Some people do not like a file that may contain a cookie with information about where they have been, and what they do, if they can stop it. This type of information that is invaluable to some companies. Cookies are usually used for simple things like to store your specification of your start page, or your user id's and or passwords, but like most things they maybe manipulated to do bad things. Cookies can be used to track you on the net, what sites you go to what you like and so on. This is not the only your tracked by big brother on the net, for instance when you submit an auto search in Internet Explorer it's routed through Microsoft servers. Cookies were originally designed to maintain state in the stateless environment of HTTP. So it made it possible to store page settings, or user ids. A cookie can contain any data that an administrator wants.
Q. How Do I Stop Cookies In Netscape?
A. In the Netscape directory there should be a file called cookies.txt (or magiccookie on the Mac). Search for this file if you cannot find it. This file is where all the all the cookie entries are found. You can delete the contents of this file regardless of the warning at the top of the page. After the contents have been deleted save the file and set its attributes too read-only, hidden and system. This will stop cookies from being set persistently on your disk, but it will not stop cookies from being set in memory while Netscape is running. When you exit Netscape these cookies will be cleared. This is probably a good alternative to have Netscape alert you when a site wants to set a cookie, as this becomes more of an annoyance than a prevention. Another good way to stop cookies is to use some software.
Q. How Do I Stop Cookies In Internet Explorer?
A. Since version 3.0, Internet Explorer no longer stores cookies in a single file, but each cookie as a separate file in the windowscookies directory. This makes it harder to stop cookies, but if you want to stop individual cookies, like the doubleclick cookies, you can corrupt the cookie by deleting the contents then saving the file and setting its attributes read-only, hidden and system. This means when you log onto a site that has set that cookie it cannot read any information off your cookie or give you a new one. In a fashion similar to Netscape you can set IE to alert you before accepting cookie. To do this go to the View Menu | Options | Advanced tag and click on "Warn Before Accepting Cookies."
