I've reproduced it on my side. This is indeed a bug. When ngx.exec()
is used after ngx.location.capture() or ngx.location.capture_multi(),
nginx 0.8.11+ will not close the client connection due to leaked
request reference counter (r->main->count). A hacky work-around is to
disable nginx http keepalive and rely on the browser (and other http
clients) to actively close the connection. And that's why wget, curl,
firefox, and other well-written http clients worked for you.

Nginx 0.7.68 (and older) is confirmed to work in this context just
because older nginx does not use reference counting.

I'll attempt fix in the next few days. Thank you for reporting this
and sorry about this issue :)

Cheers,
