Cookies created by InternetSetCookie without an expiration date are stored in memory and are available only in the same process that created them. Cookies that include an expiration date are stored in the windows\cookies directory.
Creating a new cookie might cause a dialog box to appear on the screen asking the user if they want to allow or disallow cookies from this site based on the privacy settings for the user.
Caution InternetSetCookie will unconditionally create a cookie even if “Block all cookies” is set in Internet Explorer. This behavior can be viewed as a breach of privacy even though such cookies are not subsequently sent back to servers while the “Block all cookies” setting is active. Applications should use InternetSetCookieEx to correctly honor the user's privacy settings.
