Answer 1

DWR is a great tool when your site has a lot of ajax calls.

Each page that makes dwr rpc calls needs to include :

a) an interface file corresponding to the calls being made. and b) a js file bundled with dwr that contains the dwr engine code that makes these calls possible. for e.g.

one technique that is frequently used while optimizing web applications is to use the browser cache as much as possible when a resource(like a js file) has not changed on a server.

engine.js is something that will never change unless you upgrade your dwr to a newer version. But, by default, engine.js is not a static file served by your webserver. its bundled as part of the dwr tool itsef and is served by the dwr controller/servlet.this doesnt aid client side caching.

So, it is beneficial to save engine.js under the document root of your webserver and let the webserver serve it as a static file.
