Cookies are a mechanism for storing persistent
data on the client in a file called cookies.txt.
Because HyperText Transport Protocol (HTTP) is a stateless protocol, cookies provide a way to maintain information between client requests.
Set-Cookie: name=value [;EXPIRES=dateValue] [;DOMAIN=domainName] [;PATH=pathName] [;SECURE]
name=value is a sequence of
characters excluding semicolon, comma and white space. To place restricted
characters in the name or value, use an encoding
method such as URL-style %XX encoding.
EXPIRES=dateValue specifies a date string that
defines the valid life time of that cookie. Once the expiration date has been
reached, the cookie will no longer be stored or given out. If you do not specify
dateValue, the cookie expires when the user's session ends.
Mi sembra che le pagine che sono residenti nella stessa cartella, usano lo stesso cookie.
