Hello,
I need to tailor the content based on the remote ip address.
I use the property RemoteAddr of a TRequest, but sometimes it is empty.
I see that it is a header, what I didn't see (yet, I'll trace
through the code later) is if it is sent from the remote host or is
it filled based on the ip address of the connection.
If the former, is there a more reliable way to obtain the connected
ip address?
If the latter is it a bug?
I now see that it set in TFPHTTPConnection.ReadRequestHeaders:
Result.RemoteAddress := SocketAddrToString(FSocket.RemoteAddress)
In turn SocketAddrToString returns an empty string if the address is
ipv6, but in my case it shouldn't be (the clients, firefox under
windows 10 uses the ipv4 address of the server and most of the time I
get the correct remote address, even from the same client).
Besides, it seems that the server only listens on ipv4.
I'm puzzled, I really can't see where this empty RemoteAddress could
come from.
Bye
In windows 10 when you connect to localhost, it may connect with IPV6
and route to ipv4 with weird results.
Try to connect using IP 127.0.0.1 http://127.0.0.1
You may also add in C:\Windows\System32\drivers\etc\hosts a line like
localhost4 127.0.0.1
and then http://localhost4
You may also disable IPV6 service if you don't use it. I have, because
it is seldom used, it looks like every device/system still works only
with IPV4
