Method: Nitro::Render#stream

Defined in:
lib/nitro/cgi/stream.rb

#stream(io = nil) ⇒ Object

Enable streaming mode for the current HTTP Response. You can optionally provide an existing IO object for streaming. – This code is considered a hack fix. But it still is useful so for the moment it stays in the distribution. ++
