Apache and CERN can do content negotiation on Accept: headers as per the
HTTP specifications, but they don't use the User-Agent field to make
content decisions. However, it would probably not be hard to modify
Apache's mod_negotiation.c module (in 0.8.x and beyond) to look at that
and compare it to some matrix of heuristics (i.e. invent a new server
configuration directive like
AddUserAgentAccept /*Mozilla*/ text/x-netscape-html
and have Netscape-embossed HTML pages use a ".nhtml" appendage)
If you do that let us know (apache-bugs@apache.org).
