Lighttpd

sending a request like this:

HEAD / HTTP/1.0
Connection: k

or

HEAD / HTTP/1.0
Connection: keep-alivewhatever

lighttpd thinks its keep-alive.

the problem is in buffer_caseless_compare() which returns 0 (buffers equal) if the
length differs and the first characters are equal.

resolution whould be to:

return a_len - b_len;

but i dont know if this works really correct because of:

} else if (cmp > 0 && 0 == (cmp = buffer_caseless_compare(CONST_BUF_LEN(ds->key), CONST_STR_LEN("Content-Length")))) {

in request.c, here i mean "cmp > 0".
