Hi,
Im playing around with the /boost_asio/example/http/server3
and using POST method.
The bytes_transferred is 231, but thats only the header and ends with 
\r\n\r\n, need to read the rest.
Sometimes i get bytes_transferred to 1032, the right amount of data,
sometimes i get bytes_transferred = 231, but if i print the buffer_  i have 
all the 1032 bytes.
Is it right that the bytes in the buffer_ and the bytes_transferred is not 
the same?

appreciate any help.

  {
    boost::tribool result;
    boost::tie(result, boost::tuples::ignore) = request_parser_.parse(
        request_, buffer_.data(), buffer_.data() + bytes_transferred);

    if (result)
