Redirecting with nginx
Today one of our server got in trouble with an ACE encoded IDN domain. The problem seemed to be rails in combination with nginx’s X-Sendfile feature. The result became that when accessing the site trough the IDN domain x-senfile did not send any files….
Our quick and dirty solution (until we have found the source/or solved the problem) became redirecting all traffic from the IDN domain to the domain without strange-swedish-characters.
With nginx this is as simple as in most webservers just put the following code before you original server configuration in nginx.conf.
server_name xn--svenskdomn-y5a.se www.xn--svenskdomn-y5a.se;
rewrite ^(.*) http://www.svenskdoman.se$1 permanent;
And Bowang! All requests to www.svenskdomän.se will be redirected to www.svenskdoman.se.
Domain names have been changed to protect the innocent
