in thread Plack and apache child init phase

Thanks, I had read the Plack::Handler::Apache2 doc but not the others.

I will give this a try, but...it's not clear to me how it is doing anything at child init time, not compile time.

    now you've confused me :) some more

    At what time, other than child init time, would any plackish webserver create an app object of your app and then wait for incoming requests?

    That is pretty much "child init time" in terms of PSGI ...

    So the app object is created, builder runs the "enable" callback, and then the webserver waits for requests to give to app

    Oh yeah, I see , it is no different than just doing it in the constructor :) except maybe slightly semantically different (if its not part of the app, then do nothing middleware seems appropriate)

    I think child_init_time is about knowing too much about the webserver

    PSGI is about apps, ::Middleware is about wrapping apps (daisy chain), and Plack::Handler is about connecting PSGI apps to webservers (hey random webserver run this app_

    I just can't see where child_init_time belongs as a PSGI/Plack concept ...

      At what time, other than child init time, would any plackish webserver create an app object of your app and then wait for incoming requests?

      Well, normally I want compilation to happen as early as possible; in a preforking server, this is at startup. child init is after that, whenever a new child is forked, but before actually waiting for incoming requests.
