Ember 1.13 store.query always from cache in IE11

I upgraded my Ember web application from ember 1.12.2 to 1.13.13 with ember-cli 0.2.7 and ember-data v1.13.16. Now for some models the store.query('modelname', {'something': thus.get('id')} always gives old data in IE11. When I check the REST call in IE11 I also see 'from cache'. Why? In Chrome it does get the data from te server, NOT from the cache. How can I tell in my Ember code it must NEVER get the data from cache?
