    Question Cookies and Dynamic Ajax Content

    1) Script Title: Dynamic Ajax Content

    2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...jaxcontent.htm

    3) Describe problem: I am using the script as modified in the post, http://www.dynamicdrive.com/forums/a...p/t-11279.html on two pages on one site, http://www.gethelpflorida.org on both of these pages: http://www.gethelpflorida.org/statefedresources.shtml and http://www.gethelpflorida.org/faqs.shtml. Since I am using the same script in both locations, it is sharing the cookie to put content remembered from one page as the selected content when the other page loads. Is there a way to rewrite the code so that a separate cookie is used for each page?

    4) The code: <script type="text/javascript">
