I have replaced my session cleanup code with the new session manager template. Great.
I am still concerned, though, that orphaned session memory table records will accumulate over time. If my installations were being restarted every day or even every week this wouldn't be an issue, but some of them run for months without a restart. It was my orphan clean out methods that encountered the original 'not found' compiler error.
I looked through the new netwebsessions code, but couldn't get anything to work for me. So, how do I query whether a specific SessionID corresponds to an entry in the SessionQueue?
