& is how you escape ampersands in HTML, when you want to escape it
in URLs, you must use %hex notation. i.e. %26. So, the URL should be:

http://www.greenwoodmap.com/cgi-bin/proxy.cgi?url=http://records.sublettewyo.com/mapserver/listJSON.php?ts=greenwood%26key=value

I would actually also escape the "?" and "=" just to be on the safe side

http://www.greenwoodmap.com/cgi-bin/proxy.cgi?url=http://records.sublettewyo.com/mapserver/listJSON.php%3Fts%3Dgreenwood%26key%3Dvalue

Of course, you could also just use the javascript function escape().

var proxy = "http://www.greenwoodmap.com/cgi-bin/proxy.cgi";
var target = "http://records.sublettewyo.com/mapserver/listJSON.php?ts=greenwood&key=value";
var full_url = proxy + "?url=" + escape(target);
