Hi, I wonder if there is any reason to avoid mapping several host names  
to the same rails application in an apache + fcgi configuration (I’m  
thinking about the tmp directory content).

My idea is to detect the host name and render specific views depending  
on its value, eg. [mobile.mysite.com](http://mobile.mysite.com), [www.mysite.com](http://www.mysite.com)

Thanks
