Hello,

I am trying to change my rails 1.2.6 application to rails 2.2
I have made all the other changes and able to make everything work
except upload progress.
When I try to start the mongrel server using the command

 mongrel_rails start -S config/mongrel.conf

it throws the error

** Rails loaded.
** Loading any Rails specific GemPlugins
** Loading config/mongrel.conf external config script

`run'
	from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:281

the

config/mongrel.conf contains

uri "/",
  :handler => plugin("/handlers/upload", :path_info =>
'/upload/create', :memcached => UPLOAD_PROGRESS_CACHE),
  :in_front => true

We are using memcache to store the upload progress info. This works
smoothly in Rails 1.2.6.
What has changed in the new rails version which is causing this error,
how to get it working?

Any help on this issue will be much appreciated.

Thanks in advance.
