[HtmlUnit] Simulating Browser Refresh Button

[<Mik...@su...>]

I have a need to simulate the browser refresh button.  I.e. I want to reload a
page.  I don't see a direct way to do this in HtmlUnit 1.1.  Is there something
that I am not seeing?  Assuming there is not, one simple way to partially solve
the problem is to add the following function to HtmlPage:

    /**
     *  Return the url that was used to load this page
     *
     * @return  See above
     */
    public URL getUrl() {
        return originatingUrl_;
    }

However, this will only work for pages that are a result of a HTTP Get requests.
It will work for pages that were a result of a Post request, because the URL
will not contain the request parameters.  Therefore a more complex solution is
needed to solve the problem entirely.

Thoughts?
