I’ve recently moved from nginx with mongrels to phusion passenger on apache.
I like to drop the www subdomain on my sites when I can, but the passenger chaps recommend that you don’t use mod_rewrite with mod_rails (aka mod_rack or even mod_ruby).
So how’s it to be done?
The simple solution is to do the re-write in rails. I found this snippet which does the trick (thanks to RSL):
def trim_www if request.subdomains.first == "www" if request.subdomains == ["www"] redirect_to "#{request.protocol}#{request.domain}#{request.port_string}#{request.path}" else subdomains = request.subdomains.shift.join(".") subdomains << "." unless subdomains.blank? redirect_to "#{request.protocol}#{subdomains}#{request.domain}#{request.port_string}#{request.path}" end end end
