Those concepts ("application start", etc) are not well-defined many
webserver-based programs. The point being that robust design here is to
revolve around "shared nothing" as much as possible because the
lifecycle of different processes or threads in the web server is not
tied to anything in particular. There are multiple children responding
to incoming requests, each running a copy of the code (possibly a shared
copy, but still each not tied to the others) and stopping and starting
at different times.
There is not "server start" or "application start" moment. What you are
asking for requires tying all of the different request/response threads
together into a single big ball of string and isn't particularly good
design.
Now, if you have a concrete problem you're trying to solve, best to ask
about that (in a new thread with an appropriate title) and we can
discuss solutions to that, rather than trying to emulate a fairly
non-specific feature of a different framework based on an entirely
different design and set of principles.
