The http-parser package provides a utility for parsing HTTP messages. It parses both requests and responses. The parser is designed to be used in performance HTTP applications. It does not make any system calls or allocations, it does not buffer data, and it can be interrupted at any time. Depending on your architecture, it only requires about 40 bytes of data per message stream.
