The first redirect led to http://www.hdt-essen.de/university, then it was forwarded to http://www.hdt-essen.de/?rq_AppGuid=E75D576B5558DC04319BCCE4F1A72A5C5BAC1865&rq_..., and afterwards it was sent to http://www.hdt-essen.de/studiengaenge/ before we finally managed to reach this website. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.
