Overview

A UrlGroup is a collection of related URLs, for example the URL for a search tool, with several search queries. The group is weighted (and reported on) as a whole, but individual requests are made with random elements from an array of extensions.

urls = UrlGroup.new(20, "http://www.example.com/search?",
        ["foo", "bar", "baz"])
