Attachments with a load-balanced web cluster

[Matt Flaherty]

Hi,

I've got a site with serveral Linux web servers sitting behind a
load-balancer. Uploaded attachments are often lost because sequencial
requests will span different physical machines. I've got an NFS mounted
partition that I'd like to use as the upload_tmp_dir. I'm wondering if this
is safe, though. How are the .att filenames formed? Will they still be
unique when created by a fleet of webservers?

Thank you.
