TYPO3 Core

short: I'd like to stream content.

description:
TYPO3 fetches content first (saving it in arrays first) renders it and
at the end the content is written.
In some special cases content is very large or/and needs much time
beeing fetched. In those cases memory-using and the whole way of
rendering are not able to serve the request (without AJAX) because
memory is exeeded.

request:
Id'like beeing able to hold only the footer in memory while header and
content are written directly.

consideration:
Ajax does allow requests after the page is send and will be better
because the page is rendered ready before getting the content.
Nevertheless JS is required (AFAIK) at the clientside and I thought
about a serversided solution.
