# Nginx virtual host conf
#
# * Uses cache directory configured for public/cache
# * Re-writes url for iphone user agent to /iphone (so as not to conflict with cache)
# * TODO-gabe: Same for mobile user agents
# * Redirects domain.com to www.domain.com (IMO should be the other way around; www is deprecated)
