Can't Stop Cacheing

Can't Stop Cacheing

I'm playing around with mobile sites at the moment and have a very basic two-page multipage front sheet. The second page contains a div datesandtimes_main and I inserted a script that did a pagebeforeshow to use $('#datesandtimes_main').load('datesandtimes.html');

It works fine

Only it's cacheing so if I change datesandtimes.html it will not show in the web app if I go back to page 1 and the  back to page 2 again. Or if I hit refresh. In fact, the only time it *will* update is when I change the manifest version number. 

Things I've tried:
  • including the datesandtimes.html in the NETWORK (reject) section of the manifest
  • Adding a timestamp on as a ?ts= in the .load (and it's at least trying to load different timstamped files every time according to chrome's network page)
  • Changing the .load to a whole $.ajax and setting cache to false
Now, I'm stuck!
