WebRenderer cancelling document loading

Dynamic load cancelling at runtime

Preventing specific domains from loading with WebRenderer is performed by the BrowserEvent blockLoad() method. The blockLoad() method is only effective if called within the onLoadIntercept method, due to the order in which pages are loaded.

IBrowserCanavs browser = BrowserFactory.spawnMozilla();

browser.addBrowserListener(new BrowserAdapter(){
    //Called before any document is loaded or request sent
    public void onLoadIntercept(BrowserEvent e) {
         if(e.getURL().toLowerCase().indexOf("google.com") != -1) {
                //Call to prevent URL from loading - no request is sent to Web Server if this method is called
                e.blockLoad();
         }
    }
});

An alternative to using onLoadIntercept is the IBrowserCanvas method stopLoad(). The stopLoad method can be used in the onBeforeNavigate BrowserEvent. stopLoad() will stop documents loading much like a browser stop button. Requests are usually sent to the web server if stopLoad() is used, but document downloading is cancelled. This is relevant for use in a browser Stop button but may not be suitable for automated trapping applications where browser navigation is to be filtered.
