This part of the spec is too laconic. Several questions arise and MUST be answered:

1. WHY chunked encoding?
2. HOW chunked encoding?

3. WHY chunk-extensions?
4. WHICH chunk-extensions?

5. WHY trailer?
6. WHICH trailer lines?


Cnf. e.g. httpd-2.2.8/modules/http/chunk_filter.c :

if (eos && !f->ctx) {
    /* XXX: (2) trailers ... does not yet exist */
    e = apr_bucket_immortal_create(ASCII_ZERO ASCII_CRLF
                                   /* <trailers> */
                                   ASCII_CRLF, 5, c->bucket_alloc);
    APR_BUCKET_INSERT_BEFORE(eos, e);
}

<trailers> obviously are not sent.

Another question:

chunk-size:     MUST fit a UINT
               xor MUST fit a ULONG 
                or MAY exceed a ULONGLONG and the variable MUST be a FLOAT
