Very clear explanation. Thanks, Larry.
I had started with an earlier example that used GXmlHttp with
request.onreadystatechange
var request = GXmlHttp.create();
request.open("GET", "loggerGeocodes.xml", true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = GXml.parse(request.responseText);
but then grafted in the GDownloadUrl approach as a replacement and
lost the asynchronicity.
Thanks for the pointer, I will look for examples of how to do this.
I am so used to thinking of server-side work, I have to keep reminding
myself this is happening in the /client client client/...
