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. I pass the date and time variable information from the HTML form to the javascript function and let the PHP script do the legwork for reading the XML file and storing it locally. Here is the relevent part of the PHP script: <?php if ($_GET['type'] == "rainarchive") { $url = "http://alert2.udfcd.org/cgi-bin/reportgen.new?TPT=tpt/ xml_rain.tpt&CFG=lst/fslrain.lst&TIM=tim/xml_rain.tim&YE=" . $_GET ['YE'] . "&ME=" . $_GET['ME'] . "&DE=" . $_GET['DE'] . "&HE=" . $_GET ['HE']; } //fetch XML feed from posted url $ch = curl_init(); $timeout = 60; $userAgent = $_SERVER['HTTP_USER_AGENT']; $header[] = "Content-type: text/xml"; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $header ); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); $response = curl_exec($ch); if (curl_errno($ch)) { $fl=fopen($logfile, "w"); fwrite($fl, curl_error($ch) . " url: " . $url); //write contents of error to log file fclose($fl); } else { curl_close($ch); echo $response; } ?> I'm a weekend programmer and I was able to get this working for me with the help of this group. If others see a better way to do this I'm open to suggestions as well. Good luck!
