erlang NIFs for http-parser, see https://github.com/joyent/http-parser

{ok, Parser} = erlhttp:new(),
Request = <<"GET /index.html HTTP/1.1\r\nHost: www.example.com\r\n\r\n">>,
{ok, Rest, Parser1} = erlhttp:update(Parser, Request), 
% In a pipelined connection, Rest will contain parts of the next request 
{request, Result, Parser2} = erlhttp:parse(Parser1),
% Result is now [{url,<<"/index.html">>},{version,{1,1}},{method,get}]
erlhttp:parse(Parser2),
% continue parsing with the state returned from the previous call to parse

erlhttp:parse return values:

{request, Result, Parser} finished parsing request method, url & http version

{headers, Result, Parser} finished parsing headers

{body, Result, Parser} finished parsing a body chunk

{done, Result, Parser} done parsing

{more, Result, Parser} need more data, call erlhttp:parse/2

The parser will automatically accumulate the request body. To clear the results of the request body, e.g. after writing to a file, call clear_body_results(Parser)
