Thanks, it does help :) I looked up those descriptions and wasn't really sure about what to make of it.  I appreciate your opinion!  I'll start by using SERVER_NAME and then if I run into problems i'll consider checking HTTP_HOST.

Hi, Can anyone provide examples of where $_SERVER['SERVER_NAME'] and $_SERVER['HTTP_HOST'] would differ? The only example I've found is when running on localhost becaues I use a specific port and the two variables come out as: $_SERVER['HTTP_HOST'] --> localhost:10001 $_SERVER['SERVER_NAME'] --> localhost Are there occasions where one variable will be blank and the other will be set? TIA :)
