> The layout servlet looks for an alternate layout in the request parameters, and in the context (e.g. #set($layout="...").
> It would be very useful if it would also look in the request attributes, e.g. request.getAttribute("layout"). This would allow a servlet filter to specify which layout to use, according to whatever criteria, by setting the layout as a request attribute.
> This improvement is very easy to add, and it would be oh so useful!
> VelocityLayoutServlet.java (1.4):
>     protected Context createContext(HttpServletRequest request,
>                                     HttpServletResponse response)
>     {
>         Context ctx = super.createContext(request, response);
>         // check if an alternate layout has been specified
>         // by way of the request parameters
>         String layout = request.getParameter(KEY_LAYOUT);
>         // also look in the request attributes
>         if (layout == null)
>         {
>             layout = request.getAttribute(KEY_LAYOUT);
>         }
>         if (layout != null)
>         {
>             // let the template know what its new layout is
>             ctx.put(KEY_LAYOUT, layout);
>         }
>         return ctx;
>     }
> Thanks in advance.
