- user.php was not reloaded if (session-)preferences changed eg. language via select-box in login, because we used Expires header, but did not force a different url
- (user|config|images).php now has etag on url, to force reload by browser as we use an Expires header (changed images still need Admin >> clear cache to rebuild image cache)
- preferences are now loaded via a cachable GET request
a) instead of a single request like: new egw_json_request(menuaction, params).sendRequest(true, callback, context);
b) you call: egw.jsonq(menuaction,params,callback,context)
The server callback is identical for both kinds of requests. All egw_json_response methods can be used and the callback is optional.
