IMarkupCacheKeyProvider getCacheKey
I am trying to make Wicket NOT cache html templates, but only based on a
certain system property. So if this property is off, no caching, I return
null from getCacheKey() and that seems to work great. But, I am not sure
what to do when I WANT caching.
The method takes a MarkupContainer and containerClass parameter, but I am
unsure what I am supposed to do with them. I presume I am supposed to
manufacture a key somehow. But not knowing how the key is used, I am
unclear how to generate it. Is there a default implementation of this I
could utilize? Every example I find online is just returning null in order
to achieve no caching ALL the time. But I only want it conditionally.

Hi,
The default impl is org.apache.wicket.markup.DefaultMarkupCacheKeyProvider.
So instead of implementing the interface you need to extend from this class
and return null or super.getCacheKey().
