The '0' as lb_value is needed to determine which are the main/local-workers. If we don't have this special value we need an additional config-flag with a list of the local/main-workers like in Mathias patch. Should I add an additional config-flag (I will take it from Mathias patch) or do we stay with the special '0' value? The reject value of the 'main_worker_mode' flag is for the special behavior not to balance even if no main-worker is up. Without this flag you would send a request to a non main-worker if all main-workers are in error state. When the main-workers are only a preference it might be ok to send a request to a non main-worker and lose only the session but don't send an error response. I think this was what Mathias said. But I need an error response if the main-worker is down. The 'main_worker_mode' is not the same like the 'in_main_worker_mode' var in lb_worker struct. If 'main_worker_mode' flag is set to 'reject' in the workers.properties the reject var of lb_worker struct is set to JK_TRUE. The 'in_main_worker_mode' var of lb_worker struct is set to JK_TRUE if there is in minimum one worker with '0' as lb_value. > Also it would be nice to get some documentation for the new settings. > Thats no problem, I could write a patch for the HTML-page. > Regarding jk2 - I just want to know if the current solution is ok or > what are still problems.
