Dynamic Pages and Search Engines

Ok, i have a script that creates a page that will be submitted to search engines. I had originally planned on having one line of code on the search engine page: include(http://localhost/freelance.php3?id=1); But for some reason, it doesnt work. I've tried everything, changing the php3 to php and include("freelance.php3?id=1") The only thing that works is header location("balh balh... but that redirects to the freelance.php3?id=1 page and *i think* thats bad for search engines (isnt it?) So what I'd like some info on is why my include() function doesnt work and does a header lcoation command make any difference to the search engines. THANKS IN ADVANCE
