According to TNW, Internet Explorer is the only modern web browser (Opera was not tested due to temporary issue with the test page) that is not affected by the recently found memory leak.

One of the developers has created a test site with the Google’s App Engine to demonstrate the issue.

Once the site is back online, users can reproduce the bug by following these steps:

- Request an image from a server.
- Image result contains “Cache-Control: no-store”.
- Display the image.

Instead of freeing allocated memory, none of the tested web browsers did that. Here are his tests results:

Safari 5: Failed
Firefox 4.x: Failed
IE 7/8/9: Passed

As THB said, No-Store attribute was created so browsers would not store image on the local disk. Unfortunately, this is not the case. Furthermore, it looks like the issue is not OS related and was confirmed by both Windows and Linux users.

So here you have it folks, today Microsoft has a good reason to smile about.
