How do I disable 'Transfer-Encoding: chunked' encoding in Varnish?

Question

Using Varnish 4, I have a set of backends that\'re responding with a valid Content-Length header and no Transfer-Encoding header.

On the first

Answer 1

For the time being, do_stream = false will do what you want.

Avoiding chunked encoding for the case where the backend sends unchunked is a possible future improvement to Varnish.

Example:

sub vcl_backend_response {
        if(beresp.http.Content-Type ~ "video") {
                set beresp.do_stream = false;
                set beresp.do_gzip = false;
                //set resp.http.Content-Length = beresp.http.Content-Length;
        }
        if(beresp.http.Edge-Control == "no-store") {
                set beresp.uncacheable = true;
                set beresp.ttl = 60s;
                set beresp.http.Smug-Cacheable = "No";
                return(deliver);
        }
}
