Site not working through http://itu.edu.tr address. It must redirect user to http://www.itu.edu.tr but it don't. Its very bad that university like ITU uses IIS server not Apache.
For IIS server you can use 301 redirect or something else.
Also same error with http://www.sis.itu.edu.tr - sis.itu.edu.tr not redirecting.
Page Error: ITU Proje
There is link in ITU Main Page (Hızlı Bağlantılar - Fast Access) for İTÜ Proje, it opens webpage in new tab, but there is another thing, you can't access this page. It gives error that you havent permission for this page ( http://proje.itu.edu.tr )
Also in this page error message says that you must write about this error to sistemdestek@itu.edu.tr e-mail address. But from 15.03.2011 you must write in ITU Help page about errors and etc.
If the access is only for logged users with special access rules, ITU must change its error page to give more information about this.
