non-local session support

[pmuellr]

to run on a "cloud" the session support should store sessions in some remote db, that each instance of the wiki can access. I don't see any code to do that today.

As an example, I might want to use something like this to store my session in mongo, prolly same db as my pages, different collection.

Thoughts?

Found a reference to "cookie sessions", where the session data is stored in the cookie, as opposed to some store. Downside is that you can't store that much data in there - doesn't seem to be a problem with wiki. Upside is you don't need a store - the cookie IS the store.

This seems like potentially useful node package to handle these:

So far we've only had many wikis running on one server, not one wiki running on many servers, so we haven't really felt the pressure to figure out a good solution. The db was a non starter, with the overhead it adds to setup. I agree that now that we have support for pages in dbs that it would work to have a session store in the same db, but we are not well setup to do that.

The mozilla cookie session store looks to be quite slick, and should be a drop in replacement. I can't see any disadvantages for our limited usecase, unless anyone else can I'd love to see a pull request for it.
