Upload Buffering and x-sendfile

Sorry if this is the wrong spot, the misc list wasn't helpful. This
may be a question only the devs know anyway.


Does varnish support upload (and download) buffering?

Since varnish handles all of the traffic going to and from my host I
was wondering if it buffered the client when they were uploading a
large post body or downloading a large portion of HTML.

The benefit here is that my host is not waiting for them to upload on
their slow connection and the same for download.


Does varnish support x-sendfile type responses?

It seems I might be able to program this using VCL but I was unsure so
I thought I would add it to this question. Can Varnish intercept a
header on the way to the client and redirect to a static file?

Thanks, Trey

Downloading: yes, we buffer.

Uploading: no, we don't.

Not at present, but it sounds like it could be useful, I'll add it
to the "post-2.0 ideas list".

Are there plans to offer uploading as well? Since that is the normally
the slower part of the experience.

I will put it on the "post-2.0 ideas" page and see if it sticks.
