The script could perform a DNS lookup on $ENV{DOCUMENT_ROOT}.

Always exercise caution in trusting $ENV variables though. Some are wholly unreliable much of the time, while others can be easily spoofed by a custom script trying to behave like a browser.

That means that you could be exposing yourself to a security issue by passing 'chdir' data directly from an environment variable. Put the -T switch in the shebang line of your script and watch the fireworks the next time you run it.
