Current for 2.x# KMLMany users find it necessary to include KML files on their websites, and oftenKML files are located on remote servers; especially dynamic KML. However, thecore of the [XMLHttpRequest](http://en.wikipedia.org/wiki/XMLHttpRequest)object, the Javascript convenience that allows AJAX to happen, prevents requestsacross domains.This means that a site    http://www.hello.com/cannot load KML from    http://world.com/Without a special workaround.# Proxy HostFor this, there is a special setting in every map called "Proxy Host." It isin the 'General information' tab, at the bottom of the page. You can use any ofa number of [PHPproxies](http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=php+proxy) forthis purpose, or you can use the [proxymodule](http://drupal.org/project/proxy), which integrates with Drupal.
