Why use Varnish pipe?

The documentation isn't very specific on this subject and it really only explains what happens when you call the pipe subroutine. Why would you return (pipe) in a Varnish VCL and what are some things you would do in the subroutine vcl_pipe?

Why would you return (pipe) in a Varnish VCL...?

I typically use return(pipe) to avoid Varnish timeots & post-processing of request (by example when serving huge files) [1]

Pipe also is something you should use if you want to use websockets [2]

what are some things you would do in the subroutine vcl_pipe?

I've only seen websockets instructions and the typical (default VCl includes it) connection close setting

set bereq.http.connection = "close"
