Can UPnP Discovery be done from Javascript? -

-

i'm working on webpage on want discover upnp devices, client maybe on different vlan server. so, upnp discovery needs happen on client. apparently udp not possible javascript. know if there way upnp discovery client's browser?

javascript has no built-in raw networking capabilities. example, can't natively pings. can diy ping/port scanner using img tag, , setting src attribute target , testing response. but, other that, need plugin or activex.

i suggest using java.
