Information Collected for Tracking and Customization (Cookies)

A cookie is a small file that a website transfers to your computer to allow it to remember specific information about your session while you are connected. Your computer will only share the information in the cookie with the website that provided it, and no other website can request it. There are two types of cookies: session and persistent. Session cookies last only as long as your Web browser is open. Once you close your browser, the cookie disappears. Persistent cookies store information on your computer for longer periods of time.

The ASF website may use session cookies for technical purposes, such as to enable better navigation through the site, or to allow you to customize your preferences for interacting with the site. The site may also make use of persistent cookies to remember you between visits so, for example, you can save your customized preference settings for future visits.
