2.2.1.3.2 Server

The Server Response header field specifies the software that handled the request and originated the response.

Server = "Server:" server-product-name "/" version CRLF; (see [RFC1945], section 10.14)

server-product-name = 1*CHAR

The version uses the <Major Version>.<Minor Version> numbering scheme.

Version = 1*DIGIT "." 1*DIGIT

The server sets the token value to a string identifying the server product. The implementers SHOULD set the token value to a string identifying their product and product version.<4>
