thnx poul, i must have read the documentation wrong. for my clarificaiton, if the backend specifies "Transfer-Encoding: chunked" and we are caching the file within varnish, varnish will send chunk the response to the client while simultaneously caching the file?

All varnish versions have supported that.

2.1.1 had a bug in the handling of it.

Never attribute to malice what can adequately be explained by incompetence.
