# nginx first searches for the most specific prefix 
# location given by literal strings regardless of the 
# listed order. In the configuration above the only prefix 
# location is “/” and since it matches any request it will 
# be used as a last resort. Then nginx checks locations 
# given by regular expression in the order listed in the 
# configuration file. The first matching expression stops 
# the search and nginx will use this location. If no regular 
# expression matches a request, then nginx uses the most 
# specific prefix location found earlier.
