[Zope-dev] serving BLOBs

Hi,

I know serving large BLOBs is rather frowned up using Z2, but I have a
requirement to use the zope security machinery prior to serving a blob
circa 500Mb.

I thought I'd just wrap it in an ExternalFile and it would simply stream
to the client.  In fact I was even anticipating taking advantage of
chunked transfer encoding for HTTP1.1 clients.

However, I'm getting out of memory exceptions thrown by the server.
This would indicate that no intermediate buffer flushing is occuring at all!

What am I missing?

Alan
