File.open(@containerformat.location,"rb") do |f|
pos=f.tell
while @buffer = f.read(4096)
ext = File.extname(@containerformat.streamName)
if ext == ''
extension = File.extname(@containerformat.location)
#send_to_web_app(pos, buffer)
send_data(@buffer,:filename => @containerformat.name+extension,
:disposition => 'attachment')
else
send_data(@buffer,:filename => @containerformat.streamName,
:disposition => 'attachment')
pos=f.tell
end
end
now am doing it like above and trying to download 284mb of file
but only 211 bytes of file being downloaded..
why??
