Steps:

• Login (any user/pwd will do for the test)
• In /website/get/1 , change the name
• Click Submit
• See the name is not refreshed
• F5, name is refreshed

Above steps work fine when running perl bin/app.pl
Test fails when running
sudo -u nginx /usr/local/bin/plackup -E production -s Starman --workers=2 -l /tmp/plack.sock -a bin/app.pl &

Hopefully somebody can point to what I'm doing wrong in my code. Thanks for taking the time.

Can you also show config.yml and production.yml?

So does your nginx config have "cache" anywhere?

You might add in your dancer app  header('Cache-Control' =>  'no-store, no-cache, must-revalidate');

The nginx config had no cache-specific setting.
I've tried setting the header, also setting proxy_no_cache and proxy_cache_bypass in the nginx config with same results.
I guess it can't only be nginx caching alone or I would have the same behavior with 1 starman worker.
It's the combination of whatever nginx is doing and multiple starman workers.

Try  return redirect... instead of a bare redirect
