Cookies. The
World Wide Wide is designed to be an anonymous environment. For instance, when
you connect to most Web pages, you aren't asked for a username and password the
way you are when you log onto your Email account. Typically, when you request a
page, the server that supplies the page takes little interest in who is asking,
but just pushes that page back to you. This works fine the majority of the
time, but sometimes it is useful for a page to remember something about you.
For instance, you may have gone to fill out a form on the Web and discovered
that some of your information has already been filled in. Chances are that that
was performed by a cookie
A cookie is bit of data that is stored in a cookie file in
your browser's directory. This file (and only this file) can be modified when a
page requests a change or addition. The page can only request changes specific
to that page, i.e., one page cannot change the cookie settings for another
page.
Typically a cookie will save things like a user name or
other frequently used information that a visitor doesn't want to re-enter each
time they visit a site. The cookie file can't be read from anywhere but the
machine it resides on, so there is no security risk from someone getting a hold
of this information.
