This seems to be quite kosher to me, at least according to the HTTP spec.
The June 1993 draft does not go into detail on the Server: field, but it
seems logical to follow the same semantics as User-Agent in the request,
which would be:
<field> = Server: <product>+
<product> = <word> [/<version>]
<version> = <word>
So the example you gave above would be perfectly legal. Don't be like
some browsers and send multi-word things like 'Blah blah blah for the blah
blah blah system vXXX.YYY' Someone posted a list not too long ago
detailing which browsers actually conformed to the User-Agent requirements
- percentage-wise, it was discouraging. :) Let's not duplicate it on the
server side.
