<guess>

here's the key the the answer you're looking for:

	Transfer-Encoding: chunked

for wise browsing software, these numbers are used in
re-constructing the original html from the chunks as they
arrive.

if you're just sending your stuff to an average joe running a
standard web browser, they should all understand this stuff out
of the box. if you're doing something fancy (proxy filter,
maybe?) perhaps you need to check the specs for the HTTP/1.1
protocols and accomodate them. :)
