Limit download speed in ASP.NET Core 7

Question

Is there a way to limit file download speed in ASP.NET Core? I have a website that lets users download a large-sized file. But I want to limit the file download speed for users that are not logged in to 100kb/s. Is it possible?

Also, I've checked some solutions, but those were all for asp.net mvc.

This is my method:

public IActionResult OnGet (int id)
{
    if(user is authenticated)
           //download file with unlimited speed;
        else
           //download file with limited speed;
}

EDIT: I also have checkedthis URL. But its problem was that it waited till the byte processing was complete, then started the download with unlimited speed; Which was not what I wanted.

Answer 1

Maybe something like this could work.

public async Task RateLimited(Stream source, Stream target)
{
    byte[] buffer = new byte[1024];
    int count;
    long written = 0;
    while ((count = source.Read(buffer, 0, buffer.Length)) != 0)
    {
        target.Write(buffer, 0, count);
        written += count;
        if (written >= 102400L)
        {
            await Task.Delay(1000);
            written = 0;
        }
    }
}
