Cookies are small files sent from a web server to your computer through your browser program. There are two types of cookies: non-persistent and persistent cookies.
A non-persistent cookie enables a web site to temporarily keep information on your computer as you travel from one page to another on our web site. This cookie is automatically deleted from your machine when you close your browser. Because these cookies are necessary to provide some functions, failure to allow such cookies may make some of the functions on our web site unavailable to you.
A persistent cookie is kept even when you close your browser. You can manually delete these cookies using commands specific to your browser and computer system. These cookies store information that would generally not change from session to session. They also contain information that would need to be reentered by you each time you visit the web site. For example, a common use of persistent cookies is to allow a registered web site visitor to enter the web site without having to specify their username and password.
