See https://github.com/php/php-src/pull/694#issuecomment-267183973 ff =
and =
https://github.com/apache/httpd/commit/cab0bfbb2645bb8f689535e5e2834e2dbc2=

I should point out that right now, this does not require action on the =
PHP side, as the change will be reverted for the next Apache release; I =
started this discussion to address the fact that Apache and PHP/FPM are =
mutually depending on specific magic/workarounds, which is not easy to =
solve without some coordination :)

Are you using SetHandler, or another method? SetHandler is the only one =
that universally works with arbitrary .htaccess rewrites etc, unlike =
ProxyPass.

The issue also only arises when rewriting to e.g. an index.php
