Under normal circumstances--and ignoring any browser bugs--how can a cookie be accessed from a domain other than the one it was set for?
It cannot be done
Correct:
It cannot be done
nswer B is correct. Browsers simply do not allow an HTTP transaction that takes place on
one domain to set cookies for another domain. Doing otherwise would present clear security
implications: for example, a malicious page on one domain could overwrite your session ID
for another domain and force you to use another session to which a third party has access
without your knowledge.
