Hi David,

This may or may not be helpful for your specific situation, but I  
wrote a $_SERVER compatibility layer into Cake in the form of an env 
() function, which you can check out here:

https://trac.cakephp.org/browser/branches/1.2.x.x/cake/basics.php#L978

It's not super-comprehensive, but it covers the basics, and uses  
fallback accessors if the $_SERVER variable is disabled entirely (I  
know Yahoo! does this, as there are some advantages in reduced  
overhead).
