Subject [Bug 56188] mod_proxy_fcgi does not send FCGI_ABORT_REQUEST on client disconnect

--- Comment #14 from Luca Toscano <toscano.luca@gmail.com> ---
To add some references (still to verify):

-
https://github.com/facebook/hhvm/blob/HHVM-3.17/hphp/runtime/server/http-request-handler.cpp#L411

- https://github.com/dreamcat4/php-fpm/blob/master/cgi/fastcgi.h#L37

>From the HHVM commentary:

"""
  /* FastCGI ABORT_REQUEST prematurely terminates a request, signaling that
   * the webserver is no longer interested in processing it. The contentData
   * for such recoreds is empty. The application server must reply with
   * an END_REQUEST record to indicate that it has aborted.
   */
"""

So php-fpm seems not supporting it, meanwhile HHVM returns a 503 by default.
These are not the full spectrum of FCGI backends but two famous ones that I
know.
