Understanding ActionPack

So in order to user form_tag_with_upload_progress, it appears that I
need stuff that’s in the following:

actionpack/lib/action_view/helpers/upload_progress_helper.rb

Do I have to do something specific to get access to this stuff or is it
included automagically?

Thanks,

you proably need a javascript_include_tag. and i saw something in
lighttpd conf file about needing an additional listener for form with
upload progress, due to the multiple connections involved…
