I'm writing an app which downloads large files over http. Is there a way to set how large the chunks of data should be that come
back from the server when I create/submit the WebRequest? Or is that totally up to the server?

I've noticed that (in my case, at least), the data that I pull off of the response stream comes in 32KB chunks. But I'm not
specifying that anywhere that I know of.

I think that is negotiated between your pc and other elements of the
network, and I don't think you can influence it. I doubt that the server has
much to say about it either.

Somewhere in the process, you instantiate an IO.StreamReader, right? One of
its constructors takes a buffersize parameter, and readblock takes a count
parameter. The documentation offers some performance guidance.

That's pretty much up to the server. Only the HTTP version of the client
may have an effect here, but not at a granular level like specifying a certain
chunk size.
