Hi Ben, I am now developping a web application with Struts and its Tiles plugin. And I am considering manage the security with Acegi. But I have no idea about it is possible to use Acegi with Strtus+Tiles. Because tiles is kind of web page template, I wonder is it possible restrict part of the content of the page to be accessed rather than a url? If possible, how? Any suggestion is appreciated, thank you in advance.
