GetObject with range cause SignatureDoesNotMatch

[hailbird]

With the following code, getObjectOutcome reports SignatureDoesNotMatch. If the WithRange is comment out, everything is fine.

        Aws::StringStream range;
        range << "bytes=" << off << "-" << off + len - 1;
        GetObjectRequest getObjectRequest;
        getObjectRequest
                .WithRange(range.str())    // range is "0-5242879". Good if comment out this line.
                .WithBucket(bucketName)
                .WithKey(oid);             // the size of the object is 12M
        GetObjectOutcome getObjectOutcome = client->GetObject(getObjectRequest);

The corresponding logs are attached.

The problem is due to setting Schem as HTTP by mistake. The interesting point is it worked well without "range:bytes=....".

Does anyone know why this can't work with HTTP and how to work around it? I'm trying to do a threaded multi-part download through an HTTP proxy using GetObjectRequest::SetRange() but I can't download the first ~36 megabytes from the S3 key because of the signature error.

As I tried, you can only use HTTPS.

I've confirmed that HTTPS does make the error go away, but the odd thing with that is that I don't see the failed signature check with HTTP if I'm in a setup where I don't need my proxy. I have yet to test this with the latest build so I don't know if how the new proxyScheme field will affect this, but this still seems like a bug so I'm tempted to open up a fresh issue for it.
