No it don't work like that, what's more probably happening is that
your program is structured so that the answer can't be created until
the "end" of the "request" is read and this "end" won't appear until
eof has been received. You should make it explicit in your request
that it is finished (send two empy lines at the end of the request for
instance). If you don't manage to do that, show us your code so that
we could point out your mistake.
