<p>Using Google App Engine <strong>Memcache</strong>... Can more than one user access the same key-value pair?
or in other words.. Is there a Memcache created per user or is it shared across multiple users?</p>

<p>Memcache is shared across users.  It is not a cookie, but exists in RAM on the server for all pertinent requests to access.</p>
