Can I access HTML5 storages using HTMLUnit

Question

I've a requirement where I need to identify if any page is storing or reading from HTML5 data stores. I am using HTMLUnit to scrape through webpages. I checked in the sourceforge listing that the support for HTML5 storages has been built. Does HTMLUnit actually create objects for localStorage, sessionStorage etc? If yes, how can I access them?

I've also thought of scraping all Javascripts on the page and search for the keywords, but is there any better method than that?

a simple test could be to pass a javascript source code that does the setItem('key','value') storage and then does getItem('key') and inspect the result. If some script object is returned, it means success. something like the following:

ScriptResult result = currentPage.executeJavaScript("window.localStorage.setItem('some_key','some_value');window.localStorage.getItem('some_key');");
System.out.println("script result: "+result.getJavaScriptResult().toString());
