Reloading the image from the server

Hello,
On the display screen, when I move to the next or previous instance, it re-pulls the image from the relevant server each time. Any cache status does not work.

In the examples in the Ohif Test application, no study does not go back to the image address once it is loaded, and it works very well.

Is a change required in OHIF settings or on my own server?
I would be very happy if you help.

Ohif version number I use is 3.9,
I receive images from the server side, with wadoUri connection options.

thanks.

Hmm, it is weird, not sure why this happening, can you make a example repo for us to investigate?
