You mean buffered output? i.e. it renders it as it gets it? You can do that in
PHP if you turn output buffering on, or in Perl with NPH (non parsed
header)scripts. The only resource I can think of off-hand is the Links
application by Gossamer Threads, which uses Perl and NPH scripts when it's
building the pages. Otherwise, maybe do a search on "nph" or "non parsed header"
Also, NPH was originally introduced by Netscape. M$ never accepted the standard,
so support is a bit flaky in MSIE. You'll need to test it.
