Hosting bw file for gosling browser

We host the bw file for loading to gosling browser, and read the bw file from highglass server to gosling browser, howere, we found the bw file look strange on the track. Therefore we did lots of trouble shooting.

Here documented the problem (https://github.com/gosling-lang/gosling.js/issues/1093), basically if we read bw from high-glass server it has lots of background (seems like log-scaled) if we directly load bw file from was it look fine.

Can you help us to figure out if we can make it look the same if we also load from high-glass server.
