I've tried to set up an Apache 2.4 on Debian Wheezy to make calls to Hack/HHVM using mod_proxy / mod_proxy_fcgi according to this article.
The installation of HHVM was through the APT package manager. When I run a single .hack-file using
hhvm test.hack
with test.hack content
<?hh echo "test";
the output is as expected.
Now I start the HHVM fastcgi server using
hhvm --mode server -vServer.Type=fastcgi -vServer.Port=9001
and putting this to my testing vHost in the Apache configuration file:
ProxyPassMatch ^/(.*.hack(/.*)?)$ fcgi://127.0.0.1:9001/home/web/test/$1
After restarting Apache, I verified that it works by requesting a .hack-file which does not exists. I get a 404 Not Found from the HHVM fastcgi server, it looks different than the default Apache 404 page.
When I request my test.hack-file, then Apache starts 'loading forever'. If I kill the fastcgi in the background, it immediately stops loading and offers me the test.hack as a download with the content I entered (<?hh echot "test";).
I'm using PHP5-FPM with exactly the same ProxyPassMatch line, except the mime file extension and the port, of course. And it works perfectly there.
The error.log contains nothing special.
