[Icecast] master -> relay redirect

[Radio Blackout]

Hi,
i'm trying to setup a the http 302 redirect, but i don't know why not
working

this is the relay log:

> [2011-12-07  13:13:18] INFO main/main Icecast 2.3.2-kh29 server started
> [2011-12-07  13:13:18] INFO slave/slave_startup max file descriptors 1024 (hard limit 1024)
> [2011-12-07  13:13:18] INFO slave/update_master_as_slave adding master master.example.org:80
> [2011-12-07  13:13:18] INFO slave/redirector_add slave (1) at master.example.org:80 added

this is the master log:

> [2011-12-07  13:12:14] INFO slave/slave_startup max file descriptors 1024 (hard limit 1024)
> [2011-12-07  13:13:18] INFO slave/redirector_add slave (1) at relay.example.org:80 added
> [2011-12-07  13:13:18] INFO source/source_add_listener client is from a slave, bypassing limits

this seems ok to me, but when i connect to master there is no redirection

in both master/slave 
> Icecast 2.3.2-kh29

i'm using mplayer and watching the http debug info there is no redirection

any suggestion? the icecast conf file is ok according to the documentation

thanks in advance and sorry for my english

bye
