Re: [Cppcms-users] HTTP response and binary stream (libharu)

As BTW is shown in this example: http://libharu.sourceforge.net/how_to_use.html#Save_a_document_to_file_
 Why? std::ostream assumes that buf is NUL terminated string so it would stop on NUL, and this what corrupts the stream.
You need to use std::ostream::write, i.e.
out().write(buf,siz)
