The key here is the statement "I substituted www.imagemogul.com for
SERVER_NAME", in this case it does need to be quoted, because
'www.imagemogul.com' is not a simple word by perls definition (simple
words are things that match \w).  That being said however, replacing
SERVER_NAME with www.imagemogul.com will not do anything like what you
think it will do and you should change it back.
