Upload / Download Files in ASP.NET

Question

Ok, I'm a real newbie to an ASP file ... I have two related questions:

What are my options for controls that I can dynamically add to my web page to allow the user to upload large files> 100 MB to the server?

What are my options for controls to start downloading a large file in a web browser using the Save As dialog box so the server can generate the file and send it to the user?

I've seen examples for FileUpload controls, HttpRequest / HttpResponse controls, FileWebRequest controls ... it has never been clear if the examples are for Windows apps that scrape websites, or client-side scripts bound to buttons, or server code that acts on reverse gear. I guess I'm looking for the last ... something that I could write in the server code to trigger an interaction.

If anyone knows where I can find a clear tutorial, it will also be appriciated.
