The original server-side attempt from was close, and correctly pointed at browser/plugin behavior as the root cause — many browsers will render or hand off well-known types instead of offering "Save As." The most reliable approaches are either to ask the browser to treat the resource as a download (client-side where supported) or to serve it from the server in a way that unambiguously marks it as a download; a mix of both plus a few deployment checks gives the best result.

A simple client-side option (works in modern browsers, subject to cross-origin limits) is the HTML5 download attribute:

<a href="/files/animation.swf" download>Save animation.swf</a>

This avoids server-side header fiddling for same-origin links and is the easiest fix where applicable.

For server-side ASP.NET scenarios a concise, robust pattern is to return a file result that sets a download filename (ASP.NET MVC example):

public ActionResult Download(string name)
{
    var path = Server.MapPath("~/files/" + name);
    return File(path, "application/octet-stream", Path.GetFileName(path));
}

For WebForms or handlers, prefer streaming methods that avoid large memory use (TransmitFile / streaming) and ensure the response includes a download filename and a correct content length. Also quote filenames to handle spaces and non-ASCII safely.

Diagnostics and cautions: inspect the actual response headers (browser devtools or curl) to see what the client receives; check for IIS modules, compression, proxies or CDNs that might rewrite headers; verify the physical path with Server.MapPath and guard against path-traversal. Given that Flash/SWF has been widely deprecated and many browsers block or ignore SWF, packaging the asset (for example, ZIP) is often the most future-proof way to deliver a downloadable copy.

I changed content-type to "application/X-unknown" and it worked for me..
