Hi Didier,

Yes, I have looked into this.
It says if request has gzip then app engine will supply compressed
contents.

So in this case request does have gzip i.e.

Accept-Encoding: gzip,deflate


But it looks that it still does not send compressed data.

I am not sure what can I do to fix it.

Thanks.
