.htaccess redirect umlaut domain

Question

I am trying to redirect requests from a umlaut domain to another domain.

My following code works with ANY other domain, but not umlaut:

<IfModule mod_rewrite.c>
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} ^(www\.)?frankfurter-flöhe\.de/$ [NC]
  RewriteRule ^ http://kinderkultur-frankfurt.de/frankfurter-floehe-theaterprogramm.html [R=301,L]
</IfModule>

However, when I call the umlaut domain and then copy it from Google Chrome's address bar, I get this:

http://xn--frankfurter-flhe-zwb.de/

Although, if I use that obfuscated domain in my htaccess file instead of the "real" umlaut domain, it doesn't work either.

Does anybody have an idea how to match that domain?

Try using the NE flag, to prevent mod_rewrite from encoding the URL. For more information about NE: http://httpd.apache.org/docs/current/rewrite/flags.html#flag_ne

<IfModule mod_rewrite.c>
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} ^(www\.)?frankfurter-flöhe\.de/$ [NC,NE]
  RewriteRule ^ http://kinderkultur-frankfurt.de/frankfurter-floehe-theaterprogramm.html [R=301,L]
</IfModule>

If this doesn't work, try to use the HEX equivalent of umlaut, as suggested in: https://stackoverflow.com/questions/11107375/umlauts-in-htaccess-redirects

The UTF-8 URL with Umlaut needs to be converted into ACE encoding (ASCII Compatible Encoding).

You can use the following online tool to convert an international domain with Umlauts.

www.frankfurter-flöhe.de becomes xn--frankfurter-flhe-zwb.de and this is what needs to be used in the htaccess redirect.

Did you try with :

RewriteEngine On
RewriteCond %{HTTP_HOST} ^frankfurter-flöhe.de$ [OR]
RewriteCond %{HTTP_HOST} ^www.frankfurter-flöhe.de$
RewriteRule (.*)$ http://kinderkultur-frankfurt.de/frankfurter-floehe-theaterprogramm.html [R=301,L]
