RE: CGIDEV2 and non-buffered output

Yes, that's what I'm trying to figure out how to do in CGIDEV2. But I don't
write to stdout, CGIDEV2 does; that's one of its implementation-hiding
aspects.

There are typically two elements to buffering.
One is the application itself, in this case CGIDEV2. It normally stores all
the HTML output until the *FINI section is written. The second element is
the web server. Some web servers can be set up to buffer output also. That
may be only an Apache thing, but IIS might support it also. I don't know if
HTTP classic server does (or supports) buffering.

Loyd,

Wouldn't writing to stdout more frequently cause what you want?  I think
cgidev2 uses a large buffer and writes to stdout all at once.  But if you
were to write to stdout 1kb at a time. . . Or based on certain events. . .
??
