Description

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

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

Basically it would allow me to do something when origin server fails to connect (such as DNS error, timeout, etc)
