Question about CacheKeyTemplate

[Krinetzki, Stephan]

Hi Scott,

sadly the Key is not logged:

There is just the info that a cache key is created

If you want a direct read on it, set this category to TRACE for logging:

net.shibboleth.idp.attribute.resolver.dc.http.impl.TemplatedBodyBuilder

It will dump out the cache key it generates.

Velocity defaults to handling "invalid or non-exixtent" references to variables by just echoing through the literal text of the variable expression, so if they're all getting the same one, it's likely that expression isn't right and there is no such attribute being fed in.

Or there's a bug of course.

All my caching connectors are GET, so I have not had to try the feature.
