title: IE7 issue - cannot download streamed file when Automatic prompting for file downloads is disabled
body: <p>My application is J2EE (JSP/Servlet) based. I encounter an issue when i try to open a new window (pop-up) from JSP and call a Servlet action (e.g. Streamer.do) which streams a PDF file inside that pop-up.</p>
  
  <p>Problem: 
  While IE 7 -> Tools -> Internet Options -> Security -> Custom Level -> Downloads -> Automatic prompting for file downloads is Disabled and while pop-up window get opened, I am unable to download the file (Save/Open prompt is not comming up).</p>
  
  <p>In contrast, when I enable this option, I am able to download. But this option sometimes would be disabled in some environments.</p>
  
  <p>While testing this in Mozilla Firefox 3.0/3/5/IE6 it is working fine without any settings change. When i check it to enable i then get the Save/Open prompt to work correctly.</p>
  
  <p>This should be problem with IE7. Can anybody help us with Javascript or any working settings which doesnt care whether the "Automatic prompting for downloads" option in IE7 is enabled.</p>
  
  <p>Any help in this would be much appreciated.</p>
  
  <p>Regards!</p>
