HI,
In my project my work units consist of two files.

One file is reused, up to several hundred times, in conjunction with a second input file which is unique.

What I have discovered is that the file that needs to be reused is deleted from the staging area, possibly sometime after the first work unit requiring this file has completed. This results in errors when a new client attaches and attempts to download a WU that requires the common file. I get errors when trying to HTTP download the common file as it's no longer in the staging area.

How is it possible to ensure the common file stays in the staging area until all work units that use that common file are complete?

I'm think this can only be achieved by staging the files on a separate external web server or perhaps S3 bucket?

Cheers
Seth

The <no_delete/> option may be what you are looking for.
