DESCRIPTION:

This javascript, in conjunction with the "cartid.cgi" server side include (SSI) script,
automatically adds the cart_id to the end of ALL links on your html pages. This makes sure
that the cart_id, once applied, is passed between all pages on the site. This will
help to minimize lost carts, especially on AOL.


IMPORTANT:

1. This javascript below must be the LAST thing on the page just before the closing </body> tag.
2. You may need to change the /cgi-bin/cartid.cgi if it's not in the cgi-bin folder
3. You MUST upload the cartid.cgi into the cgi-bin and set the permissions to 755 (read/execute)
4. You MUST have server side includes turned on at your host and your html pages must be named
   ".shtml", or you will have to ask your host to apply SSI to ".htm" and ".html" pages or this
   won't work.
5. Finally, for any <forms> on the html page, you should also have a hidden cart_id field like this:

    <input type="hidden" name="cart_id" value="">

This will also get set with this javascript.
