luis ,but do n't have option other than send_data and one thing i can do
is while downloading large files i can do it in chunks but i only
download 4096 byte ,this is my code
File.open(@containerformat.location,"rb")do
|f| @data = f.read(4096) end
ext = File.extname(@containerformat.streamName)
send_data(@data,:filename => name+extension,
:disposition => 'attachment')
end
what happening here..
