What are cookies, and why does CONCRETE.com use them?
Web sites use cookies to simulate a continuous connection to that site. This makes it more convenient for users by allowing them to visit pages within a site without having to reintroduce themselves with each mouse click. Contrary to popular fears and misconceptions, cookies were not created to spy on or otherwise invade the privacy of Internet users. Cookies contain only information that users volunteer, and they do not have the capability of infiltrating a user’s hard drive and sneaking away with personal information. The simple function of a cookie is that of helping the user navigate a Web site with as little obstruction as possible.
Cookies are small data structures used by a Web site (server) to deliver data to a web client (user); request that the client store the information; and in certain circumstances, return the information to the Web site. Web sites can thus “remember” information about users to facilitate their preferences for a particular site and allow the use of user passwords. The Web site may deliver one or more cookies to the client. The client stores cookie data in one or more flat files on its local hard drive.
Cookies allow Web sites to maintain user information across HTTP connections. The current HTTP protocol is “stateless,” meaning that the server does not store any information about a particular HTTP transaction; each connection is “fresh” and has no knowledge of any other HTTP transaction. “State” information is information about a communication between a user and a server, similar in many ways to frequent flyer profiles or option settings in desktop software. (For example, a preference for aisle or window seats is cookie-like information that a frequent-flyer program might store about its customers.) In some cases it is useful to maintain state information about the user across HTTP transactions.
If you use a Netscape browser and find you’re getting more alerts about these unique cookies than you really want to see, you can turn the alert function off by opening Netscape’s Network Preferences dialog box (under Options), selecting the Protocols tab, and under Show an Alert Before, unchecking the box labeled Accepting a Cookie.
Those using a Microsoft browser can find this option hidden within the dialogs by going to View, Options, Advanced, scrolling down to Security, Cookies, then clicking ‘Always accept cookies’.
Curious about the whereabouts of any cookies you might have downloaded? Those of you using a Netscape browser will find them in a file called “cookies.txt” in the Netscape Config folder (on a Windows machine) or inside the Netscape folder located in the Preferences folder within your System Folder (on a Macintosh). If you’re using Microsoft Internet Explorer on a Macintosh, you’ll find your cookie file(s) in System Folder / Preferences / Explorer folder / Explorer Cache. Internet Explorer for Windows stores cookies in C / Windows folder / Cookies.
You can read about what kind of information we store, why we need cookies and how we use the data by looking at our Privacy Policy.
