Subject [users@httpd] Need for an REMOTE_PROTOCOL_FAMILY environment variable ?
Date Sat, 20 Nov 2010 16:41:20 GMT
Hi folks,

This is a really, really minor enhancement, but we have REMOTE_ADDR and 
REMOTE_PORT, would it make sense to have 
REMOTE_PROTOCOL_FAMILY [Ie. either "IPv4"/"IPv6",  or "2"/"10"] to 
disambiguate the REMOTE_ADDR format ?

The IP protocol family can be reverse-engineered by checking the format 
OTOH, so this is not a really major issue, but for consistency it might 
make sense.

Or would it introduce some low-level protocol detail which has nothing to 
do here ? (after all, the REMOTE_ADDR string can be parsed by the system, 
whatever the format is)
