[Seaside] support for streamed files with Zinc adaptor?

[Esteban Lorenzano]

Hi Sven el all

I'm using Zinc-Adaptor and I need to upload files. I remember Comanche adaptor had support for streamed files (they were derived to a temporary file instead load everything in the image).
While I could configure nginx or apache to do that, I would like to be able to do it  using plain Seaside too. 
It is possible with Zinc-Adaptor?

thanks,
Esteban
