Shouldn't ap_get_remote_host use req->useragent_addr?

[Jan Kaluža]

Hi,

When httpd is running behind a reverse proxy and mod_remoteip is 
configured, the correct client IP is logged (using %a in the LogFormat), 
but the proxy IP is used by 'Require host .mydomain.net'. I would expect 
the host based on IP provided by mod_remoteip to be used here.

Is this expected behaviour? Maybe the ap_get_remote_host method should 
use req->useragent_addr instead of conn->client_addr to obtain the 
REMOTE_HOST.

Or we could introduce new env variable and new auth_provider to work 
with real remote_host of the client even when it is behind the proxy.
