Contributor(s): Tom Benner
OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";
More information on this, as well as an example CGI proxy file, can be found here.
If CGI execution isn't readily available, a simple PHP script can be written that takes a URL as a GET parameter and echoes the contents of that URL.
