I've been pretty busy of late so had no time to keep track of the
list. My apologies.

Still, I would be happy to try and resolve this.

Since this was last month, I'm assuming there might have been changes.
Can you tell me what the last current state (plus some code, please)
of this is? We'll pick it up from the current state and try and
resolve any issues.

I guess the basic issue that happens is what is described above and for some reason for me, Starman doesn't seem to solve it.

A basic example I will give is this, and keep in mind, this is a single user, not multiple at this stage.

Load up the home page of the website, there are processes that run that might take 4-5 seconds to complete in the background (using jquery) (let's call it /LoadPage).
The I click on a page to generate a report (say /LoadReport), however, the report waits for /LoadPage to fully complete before starting (on the server side, I can see the client sending through the request immediately), thus it is completely blocking. It seems to do this even when running through Starman.

I'm not sure if there is a way (or if this even makes sense) to fork out each request so the dancer site isn't just sitting there waiting for the last thing to complete.

I tried using the Delayed responses (Async/Streaming) listed here:

https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Manual.pod#Delayed-responses-Async-Streaming

But for some reason, maybe because it is solving a problem that I don't specifically have, it didn't seem to help.

Also, I pretty much all the time run with -R (or the equivalent restart switch for plackup/starman) so the site restarts without me having to intervene if any of the files get modified, I'm not sure if that factors into the forking issue I have.

Thanks,

David
