UrlEncodedQueryString represents a www-form-urlencoded query string in Java. I can’t tell you how many times I’ve needed this in the past. Perl has the lovely URI::QueryParam. In fact, I’ve got a fairly close cousin of this class in use at $WORK (though it uses google collections as I’m lazy).
Now it just needs to appear on a maven repository somewhere…
