## ServerSignature

Syntax: ServerSignature Off | On | EMail
Default: `ServerSignature Off`
Context: server config, virtual host, directory, .htaccess
Status: core
Compatibility: ServerSignature is only available in Apache 1.3 and later.

The ServerSignature directive allows the configuration of a trailing footer line under server-generated documents (error messages, mod_proxy ftp directory listings, mod_info output, ...). The reason why you would want to enable such a footer line is that in a chain of proxies, the user often has no possibility to tell which of the chained servers actually produced a returned error message.
The `Off` setting, which is the default, suppresses the error line (and is therefore compatible with the behavior of Apache-1.2 and below). The `On` setting simply adds a line with the server version number and ServerName of the serving virtual host, and the `EMail` setting additionally creates a "mailto:" reference to the ServerAdmin of the referenced document.
