  • Expires − The date the cookie will expire. If this is blank, the cookie will expire when the visitor quits the browser.
  • Domain − The domain name of your site.
  • Path − The path to the directory or web page that set the cookie. This may be blank if you want to retrieve the cookie from any directory or page.
  • Secure − If this field contains the word "secure", then the cookie may only be retrieved with a secure server. If this field is blank, no such restriction exists.
  • Name=Value − Cookies are set and retrieved in the form of key-value pairs
