Thanks Peter den Haan and Tim Holloway,

I am still unclear.
I understood that there status and headers before attached entity.
Some are optional headers.
Headers have variable/unpredictable content...
So, attached entity doesn't start after the end ... but where?
Might be status and headers are embedded inside fixed length envelopes or transmitted separately???
I donno, I am just a damned beginner.
