No. "inprocess" caches are local / private to the FS instance. Historically, the name was chosen to contrast it with the memcached based cache, which was out-of-process. Today, that name can be misleading. With 1.9, we may use membuffer caches for everything (each txn would use its own namespace) and maybe even drop alternative svn_cache__t implementations. But I'm not too eager to do that. -- Stefan^2. -- *Join one of our free daily demo sessions on* *Scaling Subversion for the Enterprise <http://www.wandisco.com/training/webinars>* * *
