What do you mean not all the data is sent at once? I'm doing a http
request, the browser responds sending back the code for the page.
I've never heard of it sending back multiple responses. Plus I'm
controling what the server sends from the ISAPI code, I'm only sending
info back once. I'm kinda confused on this whole not sending all the
data at once.

That's just the way how our network works :)
HTTP is over TCP/IP.
TCP/IP sends data in packets, each package is max. 1500 bytes.
So, when your server sends a site of let's say 1200 bytes then all
data will be in one single packet. But when your site returned is more
then 1500 bytes, your site will be split across multiple packets.
Reading with fread stops after a package is available...
This is also noted in the second warning on the fread manual page[1].
