Problem when downloading files with xsendfile

Hii All, i loaded in apche , i added few line in
httpd.conf files

LoadModule xsendfile_module modules/

XSendFile on

XSendFileAllowAbove on

<VirtualHost * localhost:80>
ServerName src

DocumentRoot C:/InstantRails-2.0-win/rails_apps/src/public/

ProxyPass / http://localhost:3000/

ProxyPassReverse / http://localhost:3000/

now in my rails application i have a streams controller and inside
streams controller i have a function named download ,code for code
download is below

def download

@stream = Stream.find(params[:id])

filename = “#{@stream.location}”

response.headers[‘Content-Type’] = “application/force-download”

response.headers[‘Content-Disposition’] = “attachment;

response.headers[“X-Sendfile”] = @stream.location

response.headers[‘Content-length’] = File.size(filename)

render :nothing => true


Problem is my rails application still handling this request but i would
like apache to handle this request ,can anyone tell me how i configure
apche to handle this request??

Actully when i downloding files,mongrel rendering things,

Processing StreamsController#download (for at 2010-09-27

It is when i am trying to download 2.2GB of file ,file is downloaded
completely,but my worry is why mongrel is rendering things if apache is
handling download
