Eh. I think you're confusing things here. There is no header named
'REMOTE_ADDR' in a regular HTTP request (be it get or post or others).

REMOTE_ADDR is usually an enviornment variable set by the web server before
CGI scripts/programs are invoked. The address it picks is probably picked
from the IP layer.

While you *can* set a header named that with curl, I don't think it'll make
any difference at all to what the environment variable will be set to.

Yes, as the 'HTTP' prefix suggests, those variables are picked from the HTTP
request itself. The ones without HTTP prefix are not.
