Dynamic MapService creates cache in arcgisoutput directory even if caching is disabled

[MaximeDemers]

Hi,

I have noticed that some of my dynamic MapServices published on Enterprise 10.6.1 are automatically caching the map images and legend symbols in the arcgisoutput directory of the service.

For instance, _ags_map2f122ea0f38e4d31b3d5d40371eee940.png is an example of a cached map image and _ags_legend_f171075727684b9793028c338688ded8.png is an example of cached legend symbol.

The cache parameter of the service is disabled but a lot of png are cached in that directory each time someone use the map service in a map.

In the web app builder map, I can see in the developer tools that the requests are made to the cached png instead of the dynamic map service.

Why is this happening? How can I stop that?

Thank you!

@MaximeDemers could you give information on how you disabled caching for these services?
