ap_get_brigade is designed to be used in input filters.
If you want read request data in your content handler, you
must use ap_should_client_block and ap_get_client_block.
There are lots of modules that ship with Apache that are using
ap_get_brigade, and the source code for ap_get_client_block specifically
warns against using ap_get_client_block. So, I believe the above is not
true.
In 2.2.2 ap_get_client_block is the official api, i believe the same in
2.2.8, my opinion is to
obey apis or once you get into trouble when upgrading.
The modules using ap_get_grigade happen to come from the authors of the
api, so it looks
like they just now, how to navigate "under the surface" of the api.
