Cookies are small bits of information that stateless protocols like HTTP use to maintain some persistent information across requests. A cookie is set by a remote server when it replies to a request and it expects the same cookie to be sent back when further requests are sent. QNetworkCookie holds one such cookie as received from the network. A cookie has a name and a value, but those are opaque to the application (that is, the information stored in them has no meaning to the application). A cookie has an associated path name and domain, which indicate when the cookie should be sent again to the server. A cookie can also have an expiration date, indicating its validity. If the expiration date is not present, the cookie is considered a "session cookie" and should be discarded when the application exits (or when its concept of session is over). QNetworkCookie provides a way of parsing a cookie from the HTTP header format using the QNetworkCookie::parseCookies() function. However, when received in a QNetworkReply, the cookie is already parsed. This class implements cookies as described by the \l{Netscape Cookie Specification}{initial cookie specification by Netscape}, which is somewhat similar to the \l{RFC 2109} specification, plus the \l{Mitigating Cross-site Scripting With HTTP-only Cookies} {"HttpOnly" extension}. The more recent \l{RFC 2965} specification (which uses the Set-Cookie2 header) is not supported. \sa QNetworkCookieJar, QNetworkRequest, QNetworkReply */ /*!
