I'm sorry, but there is no text about it. I only find this here:

10.14 Server

The Server response-header field contains information about the
software used by the origin server to handle the request. The field
can contain multiple product tokens (Section 3.7) and comments
identifying the server and any significant subproducts. By
convention, the product tokens are listed in order of their
significance for identifying the application.

Server = "Server" ":" 1*( product | comment )

Example:

Server: CERN/3.0 libwww/2.17


and this here:

The most common form of Request-URI is that used to identify a
resource on an origin server or gateway. In this case, only the
absolute path of the URI is transmitted (see Section 3.2.1,
abs_path). For example, a client wishing to retrieve the resource
above directly from the origin server would create a TCP connection
to port 80 of the host "www.w3.org" and send the line:

GET /pub/WWW/TheProject.html HTTP/1.0

followed by the remainder of the Full-Request. Note that the absolute
path cannot be empty; if none is present in the original URI, it must
be given as "/" (the server root).



What do you mean? Please give me an example for it.
