Very simple question here. Knowing about cross domain cookie security, does the same apply to sub domains?
EG. Should I be able to read a cookie set on some.abc123.com from the sub domain of http://www.abc123.com?
Cookie domains are suffix matching, so cookies of
www.abc123.comwill not be sent on the site ofsome.abc123.comand visa versa.To have cookies be sent on both domains you should use
.abc123.comas the domain.
