Ayende Rahien commented on NH-813:
----------------------------------

I don't think that the string is going to cause any significant issues, and I don't think that we should change NH to fit the cache.
I just run into the same issue today, so that was happy timing

> The CacheKey derives from IdentifierSpace, which is EntityMetaModel.RootTypeAssemblyQualifiedName.  This name contains spaces, which causes an issue with MemCache, in the 'set' command.  With the spaces in the key, an invalid command is sent to the memcached server.
> I have provided a patch that exposes a new property on EntityMetaModel, RootName (to match the property name in Hibernate), which simply replaces the spaces with underscores '_'.  Now memcached caching works fine.
