persistence objects, cookies follow the "same-origin policy" because of security factors. Therefore, cookies created on a server domain can only be accessed in this domain. By default, the value of domain is the host name of the server where the cookie is created, and the domain is set up as a subdomain to restrict the cookie from being accessible only under a subdomain. However, the browser does not allow the cookie to be set to a domain other than the server's domain.(4) security. is a Boolea

If a cookie is marked secure, it passes data to and from the Web server over HTTPS or other security protocols. However, setting the secure property does not mean that others cannot see the cookie that is stored locally on your machine. In other words, setting the cookie to secure only guarantees that the data transfer process between the cookie and the Web s

The CA generates a certificate after it digitally signs Susan's public key (and other information).After Susan sends the certificate to Bob,
