Plack | PSGI toolkit and server adapters

I am debugging an HTTP Client with Plack, where the plack server listens on port 80 and the client sends request. How can I see the client request using Plack? I am trying to do something like this:

I want to use sockets. I'm using this package:

https://github.com/tlaverdure/laravel-echo-server

because my domain name has a SSL I should add this config:

https://github.com/tlaverdure/laravel-echo-server#alternative-ssl-implementation

I have two applications on the same domain, but they are both creating a plack_session every time the user logs in. It happens because application A overwrites application B's plack session.

It's a complex process to remove one of them and make them use one that is created by a central application, but for now, how can I change one of those 'plack_session' names to something like 'plack_session2' so they don't see each other?

I don't even know if it is possible.

Here is the document for Plack Session, but I can't see anything that can help me here.

Given the following handler (straight from https://metacpan.org/pod/Plack::Handler::Apache2)

Tried to handle errors in delayed response.

Every time i send [200, [ 'Content-Type', 'application/json' ] and got error before flushing the other things like that

$w->write("MyData");

$w->close();

i've got a warning in stdout and error in stderr, but page keeps loading.

it'll be loading until i stop app or stop page loading by hand.

how i can stop loading page in code or how to correctly handle errors in such apps where i use delayed response?

Perl version 5.24 Kelp version 1.02 Running Plack with Corona.

We're handling error throwing Exception::Class. Catching errors with Try::Tiny.

Also tried eval and others things, but it doesn't work. But changed Try::Tiny -> TryCatc and return if got any error, but i need write return for every catch block, it looks very bad

I'd like to be able to gracefully restart the Minion worker I am working on developing (i.e.: without gong back to the command line, killing it and restarting it, which is what I do now).

Is that possible? I'm hoping for something similar to what one can do with a Plack server, i.e.: sending a HUP signal restarts the server.

I am using CGI::Fast to leverage the speed and scalability of FastCGI, and I also CGI.pm's query string parsing. I do not use CGI.pm's deprecated HTML writing functions.

Stopping the use of CGI.pm is strongly advised in the community, but in my use case, should I also be thinking of migrating away? And if so, how do I

1) still leverage FastCGI

2) grab query params

...without adopting a framework like Dancer or Mojolicious?

The code I am looking at replacing is just:

I want to deploy a PSGI based web application by using an uWSGI gateway interface.

To accomplish this I installed Perlbrew locally on my Debian server where no root access is available.

I am new to perl plack/psgi. I want to access a subroutine within the perl plack/psgi loop, but it looks like if the subroutine is not being executed. Every parent variable like $number should being passed automatically like when writing a regular perl script. Do I miss something here, is that possible?
