Unable to read files behind pre-signed S3 URLs

See original GitHub issue

I’ve been using CERN S3 to redirect to pre-signed S3 URLs to avoid needing to proxy potentially large files. These files however are not readable with JSROOT as it’s not possible to sign a URL for both HEAD and GET requests.

I think the only issue is this bit of code that tries to set fAcceptRanges, would it be possible to either tollerate the request failing or, as it’s a widely used standard, detect if the URL has the S3 signing parameters.

I add another workaround with ^ at the end of the file name. It just skip 'HEAD` request, which normally used to get some basic server and file attributes. Available in master branch - would be nice if you can test it
