# proxyproto
|
|
|
|
This library provides the `proxyproto` package which can be used for servers
|
|
listening behind HAProxy of Amazon ELB load balancers. Those load balancers
|
|
support the use of a proxy protocol (http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt),
|
|
which provides a simple mechansim for the server to get the address of the client
|
|
instead of the load balancer.
|
|
|
|
This library provides both a net.Listener and net.Conn implementation that
|
|
can be used to handle situation in which you may be using the proxy protocol.
|
|
Only proxy protocol version 1, the human-readable form, is understood.
|
|
|
|
The only caveat is that we check for the "PROXY " prefix to determine if the protocol
|
|
is being used. If that string may occur as part of your input, then it is ambiguous
|
|
if the protocol is being used and you may have problems.

# Examples
|
|
|
|
Using the library is very simple:
|
|
|
|
```
|
|
|
|
// Create a listener
|
|
list, err := net.Listen("tcp", "...")
|
|
|
|
// Wrap listener in a proxyproto listener
|
|
proxyList := &proxyproto.Listener{Listener: list}
|
|
conn, err :=proxyList.Accept()
|
|
|
|
...
|
|
```
