PHP 5.4 comes with a built-in development webserver:
http://php.net/manual/en/features.commandline.webserver.php
When I try to start the server like documented everything looks fine:
php -S localhost:3000
PHP 5.4.4-2 Development Server started at Sat Dec 29 10:56:43 2012
Listening on localhost:3000 Document root is /var/www
Press Ctrl-C to quit.
When I curl localhost:3000 it works.
But It does not work with Firefox 17. The browser message is simple that it cannot connect to the website. Firebug shows the status "aborted" in the network console.
Is this a known issue? Can I change this behavior or at least debug it?
