[PHP-WIN] RE: RE: HTTP HEADER

[Randall Barber]

This is what I get:

Warning: Undefined variable: HTTP_REFERER in c:\inetpub\wwwroot\drew.php on line 3

Warning: Undefined index: HTTP_REFERER in c:\inetpub\wwwroot\drew.php on line 3
HTTP_REFERER is , , 

It is not defined and I am seriously perturbed :).  I want to use Linux so badly, but 
I don't make that decision :(.

Any other ideas?
