I'm developing a free hosting site in php and I need that on all the pages that are served by the server a banner should appear on top and bottom of the page.I understood that there is an auto_append directive in apache conf but I didn't find a clear tutorial about it.
Another thing is that users might upload their pages as frames. So I can't just add in the beginning and end of the page the banner.I have to detect that and put the banner inside one of the frames.
Does anybody have an idea how could I do it?
