Cookies: Frequently Asked Questions (FAQ's)

What is a Cookie?

A “cookie” is a small piece of information that is sent by a web server to be stored on a web browser, so that it can later be read back from that browser the next time this unique visitor returns to that web server. This becomes useful for having the browser remember specific information about this visitor like location of their last visit, time spent, or user preferences (like style sheets). The cookie is a text file that is saved in the browser’s directory and is stored in RAM while the browser is running. Also, the cookie may be stored on the computer’s hard drive once you log off from that web site or web server.

What are Cookies used for?

One use of cookies is for storing passwords and user ID’s for specific web sites. Also, they are used to store preferences of start pages. On sites with personalized viewing, your web browser will be requested to utilize a small amount of space on your computer’s hard drive to store these preferences. That way, each time you log on to that web site, your browser will check to see if you have any pre-defined preferences (a cookie) for that unique server. If you do, the browser will send the cookie to the server along with your request for a web page. Microsoft and Netscape use cookies to create personal start pages on their web sites. Common uses for which companies utilize cookies include: on-line ordering systems, site personalization, and web site tracking.

Site personalization is one of the most beneficial uses for cookies. For example, a person comes to the CNN site, but does not want to see any business news. The site allows the person to select this choice as an option. From then on (or until the cookie expires), the person would not see business news when they access the CNN web pages.

Some visitors feel it is an invasion of privacy for a website to track their progress on a site and choose to turn off cookies in their browser. While others only allow cookies to be used on sites they know like banking and investment sites that need to track your personal session variables while navigating within their web pages.

How does BNL use Cookies?

The following information about the use of Cookies were taken out of an ITD department memo that was received from DOE HQ which was forwarded to all BNL Department Chairs on 6/14/2001.

The Department of Energy (DOE), has directed BNL to review all of its websites that are publicly accessible to ensure they comply with DOE's established policy on Internet privacy. BNL websites that are publicly accessible will not use "persistent cookies" (i.e. small permanent files placed on a client by a web server) unless the following conditions are met:

  • The site gives clear and conspicuous notice of their presence.
  • There is a scientific- or business- requirement to gather data on the website.
  • There are appropriate and publicly disclosed privacy safeguards for handling the data.
  • The Laboratory's Director and the DOE provide written, personal approval.
  • Privacy policy statements are provided and displayed, even if the site does not collect information. Text that can be used in such statements is given in DOE/IG-0493.

What are Persistent Cookies?

Persistent cookies are stored on your hard drive by a Web Page server for a length of time that is set by the Web server when it passes the cookie to your browser. These cookies are used to store client-side state information between visits to a site.

What are Session Cookies?

  • Per-session cookies are used to store state information Only Within A Session. These cookies are cached only while a user is visiting the Web server issuing the per-session cookie and Are Deleted from the cache when the user closes the session.
  • Per-session cookies are frequently used by Active Server Pages (ASP) running on Microsoft Internet Information Server 3.0 or later. These cookies store session information as the user navigates to multiple ASP pages in a site.

How can I control which Cookies I want to accept?

You can order your browser to accept all cookies or to alert you every time a cookie is offered. Then you can decide whether to accept one or not.

See the Microsoft web page to help you set these options in IExplorer.


How to disable or enable...The Image Toolbar and Automatic Image Resizing Feature in Internet Explorer 6

By default, the Image toolbar and the Automatic Image Resizing feature are enabled in Internet Explorer 6. You can disable the Image toolbar and the Automatic Image Resizing feature by using the < Advanced > tab of the Internet Options dialog box.


Why do we have an INTRANET website?

From now on, when you go to, you will be automatically directed to one of two Brookhaven homepages.  If you are browsing from a computer outside of BNL, you will be directed to "External" homepage. When inside the BNL network, you will be directed to the "Internal" or "Intranet" web pages, which are BNL-Only web pages. Many groups and divisions have already started implementing this new feature. Some include the Information Technology Division (ITD), Procurement and Property Management (PPM) and Fiscal Services Division (FSD) to list only a few.

By having a homepage that is available only to employees, collaborators or on-site visitors, it is possible to provide information that is of interest to that audience, but which is either inappropriate or of less interest to the larger world audience.


What's is considered Personal Web Pages at BNL?

Some of ITD's web servers can host USER content that is "work related" (user resumes, published papers, publications, other project and experiment related links and information, etc...). This personal web space should NOT be confused with an AOL or other standard commercial ISP web hosting service. Family or other personal content can not be hosted in this web space. Inappropriate content will be removed immediately. Users will then be notified by email.

Examples of inappropriate use of BNL resources - This list is strictly prohibited and should not be considered all-inclusive; please check with the Cyber Security Office ( about your proposed usage.
