Is there anyway to configure the common logger to output to a file?

I can see one of the options when calling rackup is a placeholder for an
access log.

options = {:Port => 9292, :Host => "0.0.0.0", :AccessLog => []}

From what I can tell this isn't used anywhere.

I've tried this and it works up until you run a rackup app daemonized:

rackup config.ru > /full/path/file.log

Once daemonized the following lines are called:

    STDIN.reopen "/dev/null"
    STDOUT.reopen "/dev/null", "a"
    STDERR.reopen "/dev/null", "a"

I'm assuming this kills the outputing so it never reaches the log file. I
know the path is change to root during the daemonization.

I've experimented with commenting out the STDOUT line above and I've had
mixed results in different environments. I was hoping a solution existed
without having to touch the rack code base.

Any help would be greatly appreciated.

Thanks,
Greg

require 'logger'
use Rack::CommonLogger, Logger.new('/some/file/somewhere.log')

Hope that helps, didn't actually check it, but that's the general
direction you should go  :)

Thanks Michael! I noticed CommonLogger accepted a log param -- just wasn't
sure where to grab it from. I'll look into this today and let you know.
