Apache Reference: http_core, ServerTokens
Control Tokens Displayed in HTTP Server Header Field
Syntax: ServerTokens A
Example: ServerTokens min
Since: Apache 1.3
This directive controls whether the HTTP Server response
header field, which is sent back to clients, includes a
description of the generic operating system type of the server
(if type is ``os'') as well as information about compiled-in
modules (if type is ``full''). With a type of ``min'',
only the server version is included. This setting applies to
the entire server, and it cannot be enabled or disabled on a per-
virtual-host basis.
