> I want to add enhancement to ts_lua so I can write script to take advantage 
> of the TSRemapOSResponse() related functionality.
> here is one such example
> {code}
> function do_os_response()
>     ts.debug('do_os_response')
>     ts.http.enable_redirect(0)
>     local st = ts.http.get_server_state()
>     if st == TS_LUA_SRVSTATE_CONNECTION_ALIVE then
>       ts.debug('alive')
>       ts.http.enable_redirect(0)
>     else
>       ts.debug('not alive')
>       ts.http.redirect_url_set('http://www.cnn.com')
>       ts.hook(TS_LUA_HOOK_SEND_RESPONSE_HDR, send_response)
>     end
> end
> function send_response()
>     ts.debug('send_response')
> end
> {code}
> Basically it would allow me to do something when origin server fails to 
> connect (such as DNS error, timeout, etc)
