All about Internet Cookies

Check out our computer books!

OK, all you Microsoft bashers!  Netscape developed cookies. They did so as a means to store "state-related" (a programming term) and other information in a persistent manner. The information in a cookie survives after you disconnect from the remote server. When you connect again, that server can look up the cookie. Cookies work with CGI (Common Gate Interface) programs that reside on the remote server.

When a browser requests a URL (Uniform Resource Locator) from a remote server, the browser first searches a cookies file to see if any of that file's cookies match the URL it's requesting. The browser then sends, as part of the URL request, the remote server information contained in the matching cookie(s). Cookies allow CGI programs to store information on your computer instead of the remote one.

A cookie is a HyperText Transfer Protocol (HTTP) header that consists of a text-only string. Your browser stores this text string in its memory when called upon. This string contains the domain, path, lifetime, and value of a variable.

That variable is something a CGI script is looking for--your e-mail address, what site you came from to get to the remote server, what browser you are using, or what operating system you run. A server can get all of this information without cookies, but doing so slows the server down. This is the only information a cookie can contain, unless you fill out a form that explicitly adds other information or the remote server sends you a cookie with information it added--such as a shopping cart ID number. A cookie cannot and does not scan your hard drive.

 

Still have cookie-phobia? You have some options.

1. Delete your cookies off your hard drive routinely. Just do a search for "cookie," and you'll find where they hole up. This means that eventually, you will have to wait for new cookies to download when you revisit a site.

2. In Windows NT, set your registry such that cookies get stored in the Temporary Internet Files folder or the Temp folder. Then when you shut down your machine, these cookies get nuked. You can do the same thing with the Windows 95 version of DOS. This means that every time you revisit a site, you'll have to get new cookies.

3. Instruct your browser not to accept cookies at all. This may mean manually filling out a form to use a site, or not being allowed into a site at all. In general, cookies save you time and you lose by avoiding them.

4. In MS-Explorer 4.0, you can set your browser to prompt you before accepting cookies. This is probably your best option.

5. In Netscape Communicator, you can "Accept only cookies that get sent back to the originating server." This is a good option. You can also set it up to prompt you before accepting cookies.

 

The downside of not accepting cookies is you defeat the CGI scripts that are supposed to enhance your visit to a site--some services will not work without cookies.
The downside of accepting cookies is you can wind up with a ton of small files taking up room on your drive. If you need to add a drive, visit www.mindconnection.com's hardware section and put up with a couple of cookies that allow you to shop over on a secure server.

Not accepting cookies will not grant you anonymity--the information just takes longer to get. So it is not a privacy issue at all.

Working the Windows Desktop

The whole desktop approach ignores the fact that a computer's hard drive(s) are the electronic version of a paper filing cabinet. It also ignores the fact that people store a huge amount of files in that system. And it ignores a few dozen other facts relevant to using a computer. It's just a bad approach.

The desktop assumes you don't care what files you actually work on. It opens apps, not files, and this is the pathway to problems. You can inadvertently be revising the wrong thing, if you can even find it in the first place.

What you should do instead is use Windows Explorer. Microsoft tends to hide this, but it should be your standard interface with your computer, unless you don't mind working blind.

You can always right mouse click the Start button to invoke it, but you should add Windows Explorer to your Quick Launch bar and several other menus in Windows.

The default settings for Windows Explorer defy logic. Change these so you can actually see what files you are looking at. Enable it to show you the file extensions (unclick the insane "Hide extensions" box that is, stupidly enough, checked by default though actually there is never any reason to ever check this box). Select the option to show details. Now, you will be able to see your file size, file date, and other useful information. If you right click around a bit, you can find quite a bit of functionality in Windows Explorer.

If you haven't been using this interface previously, make a point of using it now. If you always open files from within Windows Explorer, you will always be able to see all available files and select the right one.

Use Windows Explorer to set up your filing system as if it's a paper filing cabinet. Save all files either on the data drive (dual hard drive machine) or in a folder on a single hard drive machine. Do NOT save files to the default locations. These never make any sense. They are typically within your applications, which is a dumb place to save them. That's how you end up with corrupted data files and it also makes file backups difficult.

For single-drive users, an easy solution is to create a folder called 0files as your top-level data folder. The zero means it will show up at the top of your file list, making things easy for you. Below this folder, create you filing structure. Never store anything at the root of this folder. Think of it as the shell of a five-drawer filing cabinet and don't toss stuff in the bottom. Always put files in folders that are in drawers.

With a good filing structure in place, you will always be able to find your files by simply clicking right to them. So think this out as you go and follow a good taxonomy. It's a much more effective way to work than how the zombies at Microsoft envision people working.

 

Recovering hard drive space

Even with today's huge drives, people sometimes run out of hard drive space. The steps below can recover wasted space.

  • Do a search for *.tmp files. Delete all of them. Then defrag your drive.
  • Do a search for *.bak files. Delete all of them. Then defrag your drive.
  • If you have any *.bmp files, change the format to *.jpg. This will result in radically smaller files. You need an image tool for this; if you don't have one installed already, then skip this step.
  • Set the Properties for the drive to compress files. In Windows Explorer, right mouse click the drive name. Then select Properties. Then select Compress to Save Drive Space. This could take a while, so unless you want your machine tied up for a few hours do this process one folder at a time and then do it for the whole drive.
  • If this issue is for your programs drive, then remove any programs you aren't using. Go to Control Panel | Remove Programs.
  • On your data drive, zip files you aren't using.

There are other steps you can take, but if, at this point, you are still low on disk space you really need to add another hard drive or upgrade one that's in your system. Or, another very cool option, is to add a My Ditto system. See our Review of the Dane my Ditto network server.
