Answer 2

This happens when you are behind a proxy which is running in HTTP 1.1 mode where as the client is running in HTTP 1.0. In curl command line you can add --http1.0 in the arguments to solve the issue

Answer 3

add this to your lighttpd config: server.reject-expect-100-with-417 = "disable"

restart lighttpd. cheers :)
