# hacks for swfupload with CookieStore and ActiveRecordStore. Original post was:
# see http://blog.airbladesoftware.com/2007/8/8/uploading-files-with-swfupload
#
# also need to put
# session :cookie_only => false, :only => :create
# into the controller where the files are being uploaded (change method as appropriate)
# -----------
# this goes in config/initializers/swfupload_fix.rb
#
# Slightly modified by Peter De Berdt for CookieStore and I (Joerg Battermann)
# added support for CGI::Session::ActiveRecordStore.
# 
# Make sure your SWFUpload 'upload_url' variable contains you're apps session key
# as a parameter e.g. ?_abc_session=<%= u session.session_id %>
