Description of problem: Currently fakamai do not send content-length header. In such case we do not even try to read content of response and set the content length to 0
also such response is evaluated as chunked and read of this response will fail.
For records - in april I commited to spacewalk change 73dbab3dc8f362c1280b381ffb508a67c96ff3e0 which forward body even if content length is not present in headers. But since fakamai now correctly send header I'm closing this bug.
