Yes, it would appear that there was much more to this than I originally
suspected. It would seek that there is probably plack::builder and:
builder {
mount "/whatever" => $app;
}
And maybe more. Either way this was a good for a reference (sorta, kinda, ah
maybe not even that :) ). But, I did learn some cool stuff here (I think). I
got working what I wanted to get working and am now looking at ae::redis to
stream when I want.
I should probably go back at some point and make sure I know the basics.
However, for now, getting this stuff to work is more funner.
I learned a new way to use shift here (or probably any function that uses
$_) and I have (sorta learned about closures.
Now, I'm pretty sure that what was being shifted was a method probably $req
= Plack::Request->($env); and $req was being or gets passed from builder.
I might be new here but I think this is getting ot and I've been told that
plack is a month or so from 'supported' so I'll go now. Thank yall for the
help.
