If that is not given by the markup stream it will fallback to the cache key
Aha. OK, that makes sense :)
The database-backed page is a basepage extended by other pages, so let's
say DbPage is loaded from a database, but MyPage which extends DbPage is
always the same (from the filesystem). DbPage will get the instanceid/
prefix for the cachekey, as it has no locationString, but MyPage will be
cached using the file-location-string. Since MyPage is supposed to show
different content depending on the markup of BasePage, I guess I can't
put that in the cache at all then?

and it would be very strange in my eyes if 1 stream (the same) has multiply
locations
at least the default MarkupStreams (based on files)

Hi Johan,
OK, so I need to override the LocationString to also include my unique
prefix somehow? Where should I do that?

put into cache gets the LocationString not the markupCacheKey
Because MarkupCache uses 2 maps
CacheKey->LocationString
LocationString->Markup
so that we dont get multiply markup objects for the same markup file.
(location)

Hi,
I have a virtualhosted CMS written in Wicket 1.3 where some of the pages
are loaded from the database. This is done using a custom
ResourceStreamLocator, configured in the Application#init method. This
works
good.
Different users have different templates loaded for the same Wicket page,
so I need to provide a custom cache key so that instance #2 doesn't get
the
template loaded for instance #1. Therefore I have overriden the
MarkupCache
class to be able to override the MarkupCacheKeyProvider. This also works,
my
CacheKeyProvider is consulted, but not always used for
MarkupCache#putIntoCache(). Shouldn't the key returned from the
CacheKeyProvider always be used when calling putIntoCache()?
Here is my MarkupCache implementation:
public class TornadoMarkupCache extends MarkupCache {
private IMarkupCacheKeyProvider markupCacheKeyProvider;
public TornadoMarkupCache(Application application) {
super(application);
}
protected Markup putIntoCache(String locationString, Markup markup) {
System.out.println("Putting " + locationString + " into cache");
return super.putIntoCache(locationString, markup);
}
public IMarkupCacheKeyProvider getMarkupCacheKeyProvider(MarkupContainer
container) {
if (container instanceof IMarkupCacheKeyProvider) {
return (IMarkupCacheKeyProvider)container;
}
if (markupCacheKeyProvider == null) {
markupCacheKeyProvider = new TornadoMarkupCacheKeyProvider();
}
return markupCacheKeyProvider;
}
}
And here is my CacheKeyProvider:
public class TornadoMarkupCacheKeyProvider extends
DefaultMarkupCacheKeyProvider {
public String getCacheKey(MarkupContainer container, Class clazz) {
String key = TornadoSession.get().getInstanceId() + "/" +
super.getCacheKey(container, clazz);
System.out.println("Setting key " + key);
return key;
}
}
I typically see things like this:
Setting key 1/no.sysedata.wicket.components.InfoPanelnohtml
Putting
file:/C:/Users/edvin/projects/tornado/target/classes/no/sysedata/wicket/components/InfoPanel.html
into cache
.. so it seems the CacheKeyProvider is consulted, but the key is not used
for MarkupCache#putInfoCache()
Can someone point me to what I'm missing?
Thanks!
