Hi Martin, some news... It is working when I keep a (java-code-)reference to the Resource instance in my ResourceReference. So, I always returning the same instance when wicket calls ResourceReference#getResource().
But, this is not the way it should be, right? kind regards Patrick -----Ursprüngliche Nachricht----- Von: Davids Patrick Gesendet: Freitag, 10.

But I dont know, what I do wrong. According to the blog article... I did mount my ResourceReference. The ResourceReference returns an instance of Resource which loads my image. I did override equals() of Resource to let wicket determine the correct instance. But... the code never runs through equals(). I always get an new Resource instance (getResource() of the ResourceReference is called multiple times) Due to that, my lastModified date flags I set in the Resource are (still) lost. So the browser is now able to cache, because the urls are stable, but the expire dates in request header forces the browser to load the image again. It seems the ResourceReferenceRegistry is not working correct... somehow... kind regards Patrick -----Ursprüngliche Nachricht----- Von: Martin Grigorov [mailto:mgrigo...@apache.org] Gesendet: Donnerstag, 9.
