The jsonp comet hanging request causes an ugly “download” state in browsers

Question

I use jsonp to execute comet requests in the cross-domain area, and the “download” status is really annoying.

Is there any way to suppress this with javascript?

For those not familiar with jsonp, it basically introduces a script tag, except in my case, I find the request on my server without returning the request until a later time.

At this time, the browser views my request as a download status.

I use this: http://code.google.com/p/jquery-jsonp/

Thanks in advance!
