I would move that code into get ips() instead.

[atian25]

@slaskis if x-forward-for[0] != x-real-ip then ?

[slaskis]

well in your PR you prioritise x-real-ip anyway. So if you would add that first as the first option in get ips() it should have the same effect.

[atian25]

ok, so get ips() should add x-real-ip when x-forward-for[0] != x-real-ip.

x-real-ip = '100.100.100.100'
x-forward-for = '200.200.200.200,300.300.300.300'
`get ips()` = ['100.100.100.100', '200.200.200.200','300.300.300.300']

sounds redundant, why not just use x-forwarded-for? from the cases I'm seeing x-real-ip == the first in x-forwarded-for

i'd also prefer if this logic was in a separate module. see:

• integrate proxy-addr #281
• https://github.com/jshttp/proxy-addr
• https://github.com/jshttp/forwarded
