custom cookies do not seem to work in 2.3.10

I'd like to flag this patch:

It would be great if it could be applied - we are running into it.

ps Not a complaint, but every release since 2.3.5 has had problems
that have prevented us rolling out an update. Each problem has indeed
been found and fixed by the great rails core team and community, but
it would be really nice to get an official release that we could use
in production - 2.3.11 soon?

Done. :slight_smile:
