Why is Operas default identification set to Internet Explorer?
Opera needs to identify itself as Internet Explorer, as some sites simply will not let Opera in. This includes many Microsoft sites and others. Some sites also fail without warning if the user tries to identify the browser as Opera or as an unknown browser. This is particularly true for sites running Microsoft IIS server, since Microsoft introduced a method that makes all unknown browsers fail and decided not to include Opera on the list of known browsers.
