My test have shown that this shared object is scope to the worker process. But, all additional worker process, if more than one is defined in the application pool, cannot benefit from it. So, I had to reorg some stuff in my framework to refresh the other worker process when I change the data dictionary from one worker process.

Thanks for the information
