Wow, that’s a lot of server response goodness! Feels like XML and JavaScript had a secret handshake I was never taught. That responseText and responseXML breakdown is neat—kinda like choosing between reading subtitles or watching the dub. If only setting up a gaming server was as easy as calling getResponseHeader(), but hey, that’s what HostNoc is for!
