I have the problem that i need to request data from an HTTPS API that can take a minute or two to return. I'm currently using LWP::UserAgent. This blocks my worker script (cyclic executive).

Is there any non-blocking way (or module) to run those requests without forking? E.g., start the request and poll in my worker loop? I have a lot of open file and network handles which i don't want to mess up by forking.

I was thinking along the lines of this pseudo-code:

my $bla = Some::Module->new();

$bla->get("https://example.com/api1?bli=blub");

while(1) {
...
if($bla->finished) {
    my $result = $bla->getResult();
    ...
    # Start next request
...
}
