Symfony version(s) affected

6.4.7

Description

HTTP streaming seems like a drop-in upgrade to not buffer the whole response, by simply replacing calls in controller actions from $this->render() to $this->stream(), except the web developer toolbar will not show up in this case.

How to reproduce

Call $this->stream() in a controller action in lieu of $this-render().

Possible Solution

Don't stream LOL.
