Question

How can I send some part of the web response without waiting the all rendering process finish?
I prefer do that in an Action.

I used to use Response.Buffer = false; in .net 2.0 but now with MVC 3 I don’t know how to do that.

Answer 1

You can potentially use an Action Filter to set the Buffer property.

public class BufferActionFilter: ActionFilterAttribute
{
          public override void OnActionExecuting(ActionExecutingContext filterContext)
          {
               filterContext.HttpContext.Response.Buffer = true;       
          }
}

PS: I have not checked if this works though.
