Simple. It's parse_url, from PHP, implemented in Javascript. Seen a lot of similar ones around the web, but they were all bulky code and none of them took advantage of the RegEx parser in JS.
Applied as a member of the String prototype, so just call as myURL.parseURL(); Will return a named object with naming identical to that of PHP's function.
Additional: if first argument is present, will break the querystring up into name/value pairs, unescaped, and return that instead of the raw querystriing.

String.prototype.parseURL = function(query) {
var url=this,
rx=/^((?:ht|f|nn)tps?)\:\/\/(?:([^\:\@]*)(?:\:([^\@]*))?\@)?([^\/]*)([^\?\#]*)(?:\?([^\#]*))?(?:\#(.*))?$/,
rg=[null,'scheme','user','pass','host','path','query','fragment'],
r=url.match(rx),i,q,ret={};
if (r==null) return ret;
for (i=1; i<rg.length; i++)
if (r[i]!=undefined)
ret[rg[i]]=r[i];
if (ret.path=='') ret.path='/';
if (query!=undefined && r[6]!=undefined) {
var q=r[6];
ret.query={};
q=q.split('&');
for (var i=0; i<q.length; i++) {
q[i]=q[i].split('=',2);
ret.query[unescape(q[i][0])]=unescape(q[i][1]);
}
}
return ret;
