Name

Server

Synopsis

The Server header is akin to the User-Agent header; it provides a way for servers to identify themselves to clients. Its value is the server name and an optional comment about the server.

Because the Server header identifies the server product and can contain additional comments about the product, its format is somewhat free-form. If you are writing software that depends on how a server identifies itself, you should experiment with the server software to see what it sends back, because these tokens vary from product to product and release to release.

As with the User-Agent header, don’t be surprised if an older proxy or gateway inserts what amounts to a Via header in the Server header itself.
