The code he posted is a simple proxy. What do you not know about using one? Are you still having issues? If so, what are they? Post a link to your map where you are using the proxy and we may be able to help. The proxy takes a request from the web page on the "users computer" to your domain and forwards it to the remote domain, then relays the response to the users computer so the remote feed is coming from your domain and doesn't run afoul of the cross-domain restriction. If you want to know more about proxies, investigate the information in the google queries I posted earlier. -- Larry > > Best, David > > On Dec 9, 4:47 pm, Rainman <[EMAIL PROTECTED]> wrote: > > > > > David, > > > I am doing similar calls on my site and I found (with much help from > > this community) that a very simple PHP script as a proxy solved my > > problems. > > > Here is my map:http://www.udfcd.org/FWP/LDAD/gmap.html > > > If you click on the Archived ALERT tab and click Update Map with the > > default options you will see it in action. > > > I use the this, 'GDownloadUrl("xmlproxy.php?type=rainarchive&ME=" + ME > > + "&DE=" + DE + "&YE=" + YE+ "&HE=" + HE, function(data)' instead of a > > direct call to the XML file.
