Following up on this request, as v1.9 has been released for a while, with an addition if I may:
Having different compressions (ZTSD & Brotli) for STATIC files compared to having them served as GZIP will be extremely welcome, yet what would be even greater to have these options also for DYNAMIC files/content, option which currently is only reserved for GZIP (v1.9 where Brotli has already been implemented).
Whatever I do, even with every compression option disabled (in OLS & App server alike), browser still shows dynamically generated pages served as GZIP-ed in the response header. This is also probably due to the very confusing and limited settings available in the WebAdmin, which brings me to my next request...
