InPrivate Browsing, the feature in internet explorer 8, which will allow a user to create a browsing session in which all private details like history, links visited, cookies etc would be destroyed once the session end. But this feature was not supported by the plugins used with it, most notably flash plug-in used to display videos and to place cookies.

According to adobe systems, this feature will be supported in Flash 10.1 so that no private data is stored when inprivate browsing session is used. Accordingly when the user exits the browser the flash data associated with session is also deleted.

This assumes prime importance since flash has been a major new contributor of malware content which is not detected by the browser themselves unlike the JavaScript or other traditional methods like active.
