Information Automatically Collected and Stored

When you browse through any Web site, read pages, or download information, certain information about your visit can be collected.

What is a cookie?

A cookie is a small piece of information that is sent to your browser-along with a Web page-when you access a Web site. There are two kinds of cookies. A session cookie is a line of text that is stored temporarily in your computer's memory. Because a session cookie is never written to a drive, it is destroyed as soon as you close your browser. A persistent cookie is a more permanent line of text that gets saved by your browser to a file on your hard drive.

AHRQ PSNet uses only session cookies, and we do so only so that users do not have to log in multiple times during a single visit. We do not use any persistent cookies.
