Here's the relevant code from MiniRubyWiki:

def decodeURL post
    result = {}

    post.split('&').each do
            |token|
            token = CGI::unescape(token)
            key, value = token.split(/=/, 2)
            result[key] = value
        end

    return result
end

The outer splitter breaks on the & partitions, and the inner splitter 
breaks on the =. Then the method returns everyone in one big happy map.

If you are using CGI, you'l need the 'CGI::unescape' to turn %20 into 
space, etc.
