Hi Martin, Underneath it all, GWT is using the XmlHttpRequest facility of the browser as a client. For GET requests, this is influenced by the caching-related response information your server resource exposes. Different browsers have different rules about how aggressive to be. Caching-related headers include "Cache-control," and "Expires." The ETag header exposed for a resource is also used by most current browsers to do conditional GET operations in the future; these may hit your resource and get a 304 Not Modified response.
If you do not ever want clients to cache the representation they GET (and this goes not just for GWT or XmlHttpRequest, but all user agents generally), the easiest thing to do is to send a Cache-Control: no-cache header. Have a look at this thread for more information and references on influencing client-side caching and how browsers treat it. http://www.mail-archive.com/[email protected]/msg06759.html Restlet's support for influencing caching is not good in 1.1, but some work on this is underway in 1.2. - Rob On Thu, Mar 19, 2009 at 9:43 AM, martin <[email protected]> wrote: > Hello all, > > I have used a GWT restlet client into an existing GWT application with > success. > > My problem is that when I try to access a server resource several times, > the client actually calls the server only one time! > > Let's be -a bit- more precise with the following piece of code: > > client.get(uri, new Callback() { > public void onEvent(Request request, Response response) { > ... > } > ); > > 1) calling response.getStatus().isError() returns false... > 2) but calling response.getEntity().getText() allways returns what was > provided at the first GET request. > > On the server side, the Restlet.handle(Request request, Response response) > is called at the first GET request, and is never called latter. > > I tried looking at GWT client code without finding any caching system.
