To answer this question we need to know the request type, http version, role of the application, capabilities of the application etc. For example if the client does not support persistent connections and the http version is 1.1 the Connection header is required. If the application is a proxy and is forwarding a request the Via header is required. — Martin Brown

It looks like HOST is the only required header field

It is only required in version 1.1. 1.0 does not require this.
