Well, whether or not the IFRAME page is cached when you click on the same tab repeatedly depends partially on how your server caches web pages. But as far as the script is concerned, the following line is what loads the page into the IFRAME:
Code:
window.frames["_ddajaxtabsiframe-"+contentdivid].location.replace(pageurl) //load desired page into iframe
You can try modifying that to:
Code:
window.frames["_ddajaxtabsiframe-"+contentdivid].location=pageurl //load desired page into iframe
to see if it helps cache the requested page on subsequent requests.
