That's what I'm hoping to establish.  We have a number of possibilities here:
1. A bug that affects both no-cache options.
2. A bug that affects the version you posted but not the one I'm suggesting.
3. Your report is missing something relevant, and consequently misleading.

If (1) then I want to fix it, which means reproducing it first.
If (3) then hopefully you'll get to the bottom of it, possibly with help.
If (2) then I'd favour nuking the directive.

Look at the header file.  ap_register_output_filter is from 2.0.  In 2.2
it's just a #define, with the last argument (proto flags) zero.
