Do not require chunked anymore

Targeting rails 8

Rack 3 does not have chunked anymore

Thanks for taking a look, but there is much more needed to target rack 3 compatibility than this basic change and this would break 2.x support. Please collaborate on the WIP at #325 (or even better, try testing it in your env if possible)

Among other things, the parameter and session handling needs to (broadly) conform to the spec and there are some open questions to address. The PR is close, but needs some more thought.

Thanks. I will test #325

I think I was lucky with my app as it does not have any sessions. I will test #325 with apps that uses sessions...

#325 is pretty close I think. Just needs a bit more due diligence and thought (the task list is broadly up-to-date). I havent been very motivated for the last few months, but I'm getting there 😅

If I can merge it with confidence that I haven't broke anything for Rack 2.2, it's broadly on the right track (won't need major breaking changes for rack 3 which I have missed) that would also be fine, even if it's not perfect

My personal blind spot is that I use Rack entirely via Rails but am neither a rails nor rack expert 😅

The more sophisticated jruby-rack regression tests are also via Rails. But there are many other uses, and Rails has a particularly opinionated use of Rack, as I understand it.
