Behavior Change

HTTP Parser of HTTP message header (for requests and responses) performs additional checks on value for Content-Length header, allowing values, matching BNF definition in RFC2616 (only digits), not causing integer overflow, allowed in multiple instances both in comma-separated lists and multiple Content-Length headers. An additional check introduced for Transfer-Encoding header to allow only RFC-compliant combinations for this header.
