Description

When returning the magic 444 response on a SPDY connection, nginx is closing the connection which causes the browser to experience a SPDY_PROTOCOL_ERROR. The SPDY connection should be cleanly shutdown.

The 444 status code is a special code to immediately close the connection. If you don't want this to happen - don't use it.

"immediately close the connection" should include cleanly closing the SPDY connection. Ignoring the SPDY state is explicitly NOT closing the connection, it's just being left hanging.
