Re:Re:Re: Puzzled at storeAppend. :-(

Thanks, Henrik pal!

I also try to find the answer by myself after posting the question.
I find in ftp.c, it is doing the same task as you said. After copying
data and all the "tags" of HTML, the buffer will flush. And not simply
just copying data and flush buffer, then copying tags and flush
again. :-) Am I correct?

Best regards,
George Ma
