Thanks for putting this together.

Apart from a couple of inline nitpicks, those code samples aren't particularly short. Maybe it would make sense to shorten the FAQ answer a lot, and link to a new recipe instead?

[CaselIT]

those code samples aren't particularly short

they are not, but I don't think we can shorten them more without making it difficult to follow.

Maybe it makes sense to have this here now, then we refactor this to a recepie, that includes a better version for wsgi, this one for asgi, both with also sqlalchemy option and maybe redis?

[vytas7]

I made a couple of minor tweaks, and this is now IMHO good enough to surface it in the docs.
We can always improve it later.

Once again, thanks for putting this together!

Thanks!
