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.

Thus wrote Mark,

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.
