Motivation / Background
This Pull Request has been created to improve the documentation related to
ActionController::Live
in Rails.Based on the findings from rack/rack#1619 and #38466, it has been identified that streaming responses do not work with Rack 2.2 by default, requiring users to implement workarounds in their applications.
Currently, this issue can be time-consuming for users to diagnose and resolve, at least the workaround should be mentioned in the Rails docs/guides to provide better guidance to users.
Detail
This Pull Request updates the docs to explain the issue and provide workarounds.
