mod_proxy_protocol implements the server side of
HAProxy's
Proxy Protocol.
The module overrides the client IP address for the connection with the information supplied by the upstream proxy in the proxy protocol (connection) header.
This overridden useragent IP address is then used for the
mod_authz_host
Require ip
feature, is reported by mod_status, and is recorded by
mod_log_config %a and core
%a format strings. The underlying client IP of the connection
is available in the %{c}a format string.
| Description: | Enable or disable the proxy protocol handling |

| Syntax: | ProxyProtocol On|Off |
| Context: | server config, virtual host |
| Status: | Extension |
| Module: | mod_proxy_protocol |
The ProxyProtocol enables or disables the
reading and handling of the proxy protocol connection header. If enabled
the upstream client must send the header every time it opens a
connection or the connection will get aborted.
While this directive may be specified in any virtual host, it is important to understand that because the proxy protocol is connection based and protocol agnostic, the enabling and disabling is actually based on ip-address and port. This means that if you have multiple name-based virtual hosts for the same host and port, and you enable it any one of them, then it is enabled for all them (with that host and port). It also means that if you attempt to enable the proxy protocol in one and disable in the other, that won't work; in such a case the last one wins and a notice will be logged indicating which setting was being overridden.
