Lighttpd

lighttpd with enabled mod_proxy does not pass trough the Content-Length if queried via a HEAD-request.

testing scenario:

lighttpd 1.4.6 @ 127.0.0.1:80, mod_proxy loaded

mod_proxy configuration:

proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => 8080 ) ) )
proxy.debug = 1

lighttpd 1.4.6 @ 127.0.0.1:8080, no modules loaded

$ lynx -dump -head http://localhost/index.html | grep Content-Length
Content-Length: 0
$ wc -c index.html
23 index.html

See the attached strace outputs. It's working for GET requests, but fails on HEAD requests.

I don't see something critical in the proxy.debug output:
