In my Dancer2 app I find that the session information is not stored in between file request. I am using YAML as my session store format.

e.g.

I have defined a test route to set a variable in the session and dump the settings and session variable in the template using Data Dumper in the template.

get '/test/:key/:value' => sub { my $key =params->{key}; my $value =params->{value}; session($key=>$value); template 'test';};

The result of Data Dumper is

$VAR1 = {
'engines' => {
'template' => {
'template_toolkit' => {
'start_tag' => '<%',
'end_tag' => '%>'
}
},
'session' => {
'YAML' => {
'cookie_name' => 'domain.session',
'is_secure' => '1',
'is_http_only' => '1',
'session_dir' => '/tmp/dancer-sessions/'
}
}
},

And session var is

$VAR1 = {
'a' => 1
};

At this point I expect my /tmp directory to contain a session folder but I see the following

starman@ubuntu:~/www/app$ ls -al /tmp
total 776
drwxrwxrwt  2 root    root      4096 Apr  2 14:39 .
drwxr-xr-x 21 root    root      4096 Apr  2 07:31 ..
-rw-r--r--  1 starman starman 776737 Apr  2 14:31 starman.err
-rw-r--r--  1 starman starman      0 Apr  2 07:31 starman.out
-rw-r--r--  1 starman starman      4 Apr  2 14:31 starman.pid

I am unable to figure out why the session file is not getting created. Any pointers on my mistake will be helpful

My test.tt is as follows

<%USE Dumper%>
<h1> Dumping the settings variable </h1>
<%Dumper.dump_html(settings)%>
<h1> Dumping the session variable </h1>
<%Dumper.dump_html(session)%>

The live url for this route is
