Hi,
I have a mongrel cluster with a mongrel_upload_progress … when I
upload a file, my cookie session id changes …
So on the upload form, my Session ID is say:
BAh7ByIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo%0ASGFzaHsABjoKQHVzZWR7ADoOcmV0dXJuX3RvIj8vdXBsb2FkL25vdz91cGxv%0AYWRfaWQ9M2Q0MzJiN2UtYWUxYy0xMWRjLTgzNDEtMDAxNTE3NGE0NDVj–9a36dd5853f963386ba042995bf66630c0b5734f
And when I do my multi-part form POST, after Mongrel’s dealt with the
whole upload and passes the request on to Rails, my session has changed
to:
BAh7ByIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo%0ASGFzaHsABjoKQHVzZWR7ADoOcmV0dXJuX3RvIj8vdXBsb2FkL25vdz91cGxv%0AYWRfaWQ9M2M4ZmM5YzQtYWUxOS0xMWRjLThlMWItMDAxNTE3NGE0NDVj–13fb2eb052168b2860bac39b2d14839bb9ed6979
Normal requests after that revert back to the initial Session ID … You
can see that just that last portion changes. If I don’t run a cluster -
ie on my development machine, it works fine.
Why is that?
The effect is that my user is not logged in for the upload post …
which means the filter chain redirects me to log in. 
Thanks
Joerg
