streaming of flash file works fine in chrome and FF. But not working in IE.

hi,

we are trying to stream a flash file. Lines of code is as given below. This works fine in Chrome and FF. However IE is not at all playing the flash file. Please help us to resolve this issue. 

We are using IFRAME to play flash content. If we directly point to a flash file IE is playing flash file. If we are streaming via  c# code(ashx handler file), then IE is failing play flash vedio.

Lines of code we are using is:

                          context.Response.Buffer =true;

                           context.Response.Clear();

                          context.Response.ContentType ="application/x-shockwave-flash";

                          context.Response.WriteFile(myFlashFilePath);

thanks,

Veena
