To change the content on the browser side, you need some kind of client-side technology, such as ECMA script ("Javascript") or a plugin. However, what you describe sounds to me like separate pages. Is there some way your script can initially send only the first page, but include a link (and maybe an HTTP refresh) back to the script with an additional parameter that indicates to print the second page, the third page, or whatever? So, if there's no page set, you send page 1 (with a link with page=2), but if the query string says page=3 you send page 3 and a link with page=4. This is the way all the major search engines do it, I think. If the query string says page=n, you send page n with a link to page=n+1
