    42  1. A background task "check_subscriptions" (installed in ''zzz_1st_run.py'') is run '''every 5 minutes''' to check for updates of resources which have subscriptions. This task schedules a separate, asynchronous "notify_notify" task for each resource/subscription pair which has updates.
     42 1. A background task "notify_check_subscriptions" (installed in ''zzz_1st_run.py'') is run '''every 5 minutes''' to check for updates of resources which have subscriptions. This task schedules a separate, asynchronous "notify_notify" task for each resource/subscription pair which has updates.
    4343 2. Each "notify_notify" task generates a '''local HTTP POST''' request to the subscribed controller (request format "msg"), applying the subscription filters.
    4444 3. This request is handled by the {{{S3Notifications.send()}}} method, impersonating the subscriber. The send() method extracts the new/updated records, and renders and sends the notification message(s) to the subscriber. Sending of the messages uses {{{current.msg.send_by_pe_id()}}}, which in turn uses the contact information of the subscriber stored in {{{pr_contact}}}.
