Monty, I will do my best to explain how cookies work. Basically as you go to a web site you move about within that site by leaving a trail of information. Which links that you clicked on and so on. If you answer questions, then that is sent back to the web site. At some stage you decide to leave that site and travel onwards to another site. Some time later you go back to the first site. Sites that do not send cookies, have to treat your second visit as your first. They know nothing about you. This may be fine but what about those links that you clicked or data that you gave at your first visit? If there was some way of saving that information, then the second or subsequent time that you visit a site, the site can ask if you have any of its cookies. Cookies are little bits of random data that the site sends to help it remember you. If the cookies are there then the site can do more intelligent things like avoid asking you an introductory question again. So what happens is that as the data is being recognized, the site asks your browser (Netscape IE or whatever) to save the data as a cookie on your system. The cookie will be given a name of the site's choosing and a link to say that it came from that site. The fear of cookies comes from the incorrect belief that sites can somehow ask for all the cookies on your system and thus get an "idea" of what else you have been up to. The only cookies that a site can gain access to are the ones that were made by earlier visits to that same site. How is this done? The site knows the name of the cookie it asked to save and can only ask for it again by name. It will only be given back IF the name AND the site link match. This all happens silently for most people and is a good thing. For some reason someone out there, through ignorance, decided that cookies were a bad thing. Not so. I see from James Hopkins reply below that he is one of these people. Perhaps this explanation will calm him down. If not then maybe he should confine his incoherency to other topics!
