We wanted to use HTTP Connector, and set it up. But we couldn't manage to make the app work correctly: we coudn't upload files > 60k and tweaking nginx and tomcat configuration wouldn't help. We were unable to debug the problem. With AJP connector, all features work fine. The app is developed with Vaadin 8.
We have no static files in our app because they already are served with a CDN.
We would like test nginx with AJP connector (if somehow supported!).
client_max_body_size is set to 128m
so I think the problem occurs at http level while uploading files but I can't manage to debug my system.

Which one do you prefer as both are very good and have similar features.

For which particular feature do you need ajp?
I have used several tomcats with httpd with ajp but after some horrible
errors we switched to http connector.
In case you don't need a special feature in httpd this makes also
possible to reduce the complexity of your chain ;-)
nginx (http/https/server static files) -> tomcat
