[go-nuts] net/http question

you will need to provide a custom listener to net/http.(*Server).Serve.

just wrap a standard net.Listener's Accept method with your filtering one.

type filteringListener struct { net.Listener }
func (fl filteringListener) Accept() (net.Conn, error) {
c, err := fl.Listener.Accept()
// fillter c
return c, err
}

My code now looks like this, does that mean , that i need to provide
my own net.Listen
function or i need to create variable with type filteringListener and
with type assertion
pass to it net.Listen listener ?

func server(conf Conf) {
r := http.NewServeMux()
r.HandleFunc("/", process)
http.Handle("/", r)

s := &http.Server{
Addr: ":80",
Handler: r,
ReadTimeout: 10 * time.Second,
WriteTimeout: 10 * time.Second,
MaxHeaderBytes: 1 << 20,
}

l, err := net.Listen("tcp", ":80")
if err != nil {
conf.Log.Panicf(err.Error())
}
go s.Serve(l)
select {
case <-conf.ServerClose:
conf.Log.Printf("Server thread exit")
l.Close()
return
break
}
}

Sorry, i'm not understand, how can i use this filteringListener in
net/http serve?

filteringListen still implements net.Listener interface, so it can be
passed to http.Serve.

you might want to read about struct/interface embedding in Effective Go:
http://golang.org/doc/effective_go.html#embedding

Thanks. I'm reread docs. Now all fine =).
Last question - how can i properly close unwanted connection and
retunr from Accept?
I'm write this code, but does this doing right thinkgs or i need to
close only CloseRead?

func (acl aclListener) Accept() (net.Conn, error) {
c, err := acl.Listener.Accept()
h, _, _ := net.SplitHostPort(c.RemoteAddr().String())
fmt.Printf("%s\n", h)
switch h {
"127.0.0.1":
break
default:
c.Close()
return c, errors.New("EACCESS")
break
}
// fillter c
return c, err
}
