Client IP preservation
Because HAProxy Enterprise is a reverse proxy, meaning that it acts as a man-in-the-middle between the client and server, the client's source IP address is masked by HAProxy Enterprise's own IP address in the server-side connection. That can fill server-side logs with entries that appear as though HAProxy Enterprise initiated the requests.
HAProxy Enterprise supports the following ways to preserve a client's IP address:
- Add an X-Forwarded-For header
Preserve the client's source IP address by adding an X-Forwarded-For header.
- Enable the Proxy Protocol
Preserve the client's source IP address by enabling the Proxy Protocol.
