Subject: streaming input for large requests
Date: Tue, 10 Aug 2010 23:23:12 +0100	[thread overview]
Message-ID: <1281478992.8692.15.camel@dogen> (raw)

Hi,

I'm looking to be able to get access to the request body as it is
available on the socket, so I can process uploads on the fly, as they
stream in.

The docs suggest this is possible with rack.input:

"Exposes a streaming “rack.input“ to the Rack application that reads
data off the socket as the application reads it (while retaining
rewindable semantics as required by Rack). This allows Rack-compliant
apps/middleware to implement things such as real-time upload progress
monitoring."

But to be rewindable, I'm assuming they're being stored somewhere?  I'd
like to be able to handle huge request bodies bit by bit without having
them written to disk (or worse, stored in ram!).  Is there some way to
do this?

Thanks,

John.
