Following discussion on indexing AJAX applications I have to ask if those who wonder why their GWT applications cannot be indexed if you expect search engines to index Java applets or Flash out there on the web, or compressed files and executable files? And if somehow GWT application get indexed what links do you expect to be shown insearch results--it can only be yourapp#variables. Is it not enough to have the application entry html indexed and available in results? Peter
