Hm, I figured out if I don't use these two entries: #RewriteCond %{HTTP_HOST} ^koehler\.uni\.cc [nc] #RewriteRule (.*) http://www.koehler.uni.cc/$1 [R=301,L] #RewriteCond %{HTTP_HOST} ^oubsu\.org [nc] #RewriteRule (.*) http://www.oubsu.org/$1 [R=301,L] It works fine without those..... Any idea how to make both work??
