Retrieve the cookie and welcome the user.
When retrieving cookies, you can only get those that were written for the server you are
on and written by you. You cannot read and write cookies that belong to someone else
or reside on a different server. In the last example, we got one cookie; in Example 16.3
all the cookies for this page are displayed.
