I don't think it could be useful to load a single cookie without loading th=
e rest of the cookies of the domain, as every time an HTTP request is made,=
all of them are sent to the server.
Moreover, creating a key for each cookie would also require to create anoth=
er key for the domain to avoid trying to open the wallet when no cookies ar=
e needed.

KCookieJar to store the cookies securely using KWallet.
The main problem I had writing this patch was that when a web page is requested, KIO \
ask for the cookies to kded using dbus. In the first implementations that I wrote, if \
the user took too long to open the wallet, KIO received a dbus timeout.
To prevent this, if it takes more than 10 seconds to open the wallet, the web page \
will be requested without sending the cookies (or sending the available cookies if \
there's still the plain text cookie file). If the wallet is opened after that, \
the cookies stored in the wallet will be available since then.
Because of this, the feature is disabled by default.</pre>
