Florent Cayré commented on LIBCLOUD-149:
----------------------------------------
Following code :
if key.lower() in special_header_keys:
special_header_values[key.lower()] = value.lower().strip()
should probably be patched as follows :
if key.lower() in special_header_keys:
special_header_values[key.lower()] = value.strip()
Indeed, I do not thing any header value should be lowered.
> S3 signature : Content-MD5 header value case must not be lowered
