When matching headers on the basis of a prefix, the check performed is case sensitive. However according to rfc2616 the headers should be case-insensitive (see: https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2)
This results in the AccountInformation not containing metadata given that the header response starts with "x-account-meta-" instead of "X-Account-Meta-"
