So my journey continues. I'm now trying to work on a webpage that needs to transfers files that may be as large as 10GB from one location to the other and ASP.NET 3.5 is not letting me do so with the FileUpload control.
And with little wonder. When you send the file it's buffered in memory until it's complete. Do you have 10Gb of memory on your web server? Per user?
You really need to find a better way - even if you had the memory HTTP file transfers don't checksum, or recover from dropped connections.
