Do we want to make a policy on this?  $HTTP_SERVER_VARS is deprecated, 
and thus in the future may be dropped.  On the other hand old (unsecure) 
PHP installations will not support $_SERVER.  We really should use one 
or the other not both.

Personally, I support using the $_SERVER, $_GET, etc family of 
superglobals despite some possible breakage of old PHP installations, 
because it is the preferred way, eventually we will probably have to 
migrate to it anyway, and it is more elegant.

How many installations are on PHP < 4.1.0?  If this breakage is an issue 
we can if PHP version is < 4.1.0 set $_SERVER = $HTTP_SERVER_VARS, 
$_COOKIE = $HTTP_COOKIE_VARS, etc.

Or is the consensus to wait to convert until it is necesary?

BTW - Lawrence, why are you limited to < 4.1.0?
