Sam,
Here is something that I used to achieve a serializable cookie. I was
storing cookies into memcached so I wanted to minimise the footprint of the
serialized object to maximise my cache and since (for my app anyway) most of
the cookie fields were null I used a null mask to save having to store null
references/empty fields.
Hope it's useful,
Chris.
