        The idea was to store get parameters to make bookmark handling more flexible.
        Unfortunately that didn't worked out.

        When we use ajax to trigger bookmarking the current page, we can pass the current url as parameter.
        But the url doesn't have the parameters in it when you use speaking urls (realurl, simulatestatic, ...).
        The problem is that there's no common api to decode urls and get the parameters.

        One solution would be to make the parameters available to the ajax javascript during page rendering.

        We skip all this and use a bit from the url for hashing and add the page id.
