It seems like that HHVM always wants to buffer the file before sending it to the client.
I use readfile() with an URL, that works fine on servers without HHVM but not with HHVM.
I want to offer the file (from the external URL) as a downoad to the client but without buffering it. I've tried that since hours but can't get it to work, no matter which headers I set. Is this a bug?
And before you ask, there is no code needed to answer such a question in my oppinion.
