Rails RestClient MultiPart Post

Question

I have a spooling app that sits between a Ruby on Rails app, and a few Pandastream instances. Prior to the creation of the spooling application, the Rails app posted it's file data straight to Panda without issue.

I've got the spooler receiving the file information and connection to the appropriate instance to pass the file data on, but I'm hoping to avoid having to save the file locally for the spooler, and be able to just pass on the file that was "upload" from the Rails app.

Is there a plugin similar to RestClient (or a way to make REstClient do this) that can support passing on a file that has been submitted via a post request without needing to save a local copy?

Thanks!
