Is gzip compression possible when saving an html plot with htmlwidgets / saveWidget

[vertesy]

Hello,

I regularly create large 3D scatter plots (100K points) and save them with htmlwidgets / saveWidget.
They are very big files that take up quite a bit of disk space (together e.g: 0.5GB).

I noticed that they can be compressed externally by gzip to save ~2/3 of the space, but browsers cannot just open them (by decompressing to cache).

I also found that html files can have internal gzip compression of the content. Can I control this from R?

Thanks
Abel
