Hi ! For future changes, it would be reasonable good to add "T/Thread" to the patterns class, which explicitely output the thread-id as a number. Its a pain with the threadpool threads, which are all named "Thread Pool Thread" (or something like this) in Asp.Net. Regard the spelling "T" or "Thread". To always apply a context method for this, isn't too good ... Thanks anyway and best regards, Manfred
