All, I’ve a problem configuring rails app to run in a subdomain. I’ve set up an application that runs on sth like: [http://mydomain.com/shop/public/admin](http://mydomain.com/shop/public/admin) which points to /home/myhome/webroot/shop/public/admin where “shop” is the rails app directory - and it works fine. But when I use my ISP’s web configuration utility to set a subdomain like [shop.mydomain.com](http://shop.mydomain.com) to point to /home/myhome/webroot/shop/public then when I go to [http://sklep.klubwina.pl/admin](http://sklep.klubwina.pl/admin) I get: Application error Rails application failed to start properly and in the apache error log I can see: mod\_rewrite: maximum number of internal redirects reached. Assuming configuration error. Use ‘RewriteOptions MaxRedirects’ to increase the limit if neccessary Does anyone know how to correct this? Thanks, Maciej. ---

Nevermind! Adding / before dispatch.cgi in .htaccess worked. Maciej.
