hey, another question!  
i’m including a redirect script (in php) for all of my pages - i have three different domain names… two of them are aliases to the third.  
so i placed the script in the header and it works on all of the pages except for… guess who? you got it - the index page! i get the error that the page has already sent out header information, but of course, it hasn’t - it’s on the first line of the page… and it works on all other pages with the same exact include file…  
any ideas? can this be because of the alias or something?
