Reload previous page on back button - using cache control

Question

Hi,
In my application I am using cache control to avoid the pages to be cached. But the requirement is changed and now the previous page can be re-loaded on hittinh browser's back button even after the 10 mins. i.e if user hits the back button with in 10 mins he should be allowed to see the pre-loaded contents on the previous page. After 10 mins the browser should display the page refresh warning.
a) Old code to preventing caching:
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0     
response.setDateHeader ("Expires", -1); //prevents caching at the proxy server
b) I am trying with the code ha changes as to get the previous page with in 10 minutes time:
response.setHeader("Cache-Control","no-cache, max-age=600"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0     
The above code changes are not working. If uses "no-cache" with max-arg=600 it behaves like the code in section a).
If I uses response.setHeader("Cache-Control","max-age=600"); then even after 30 mins it load the previous page with preloaded contents.
Any help is appreciated.

I tried it lots of time by refreshing the browser's cache. I am using IE 6.0. I tested it through FireFox to get the header details. when I submit the request it displays the headers request
same as I set in the code. But when I hit the back button (after the max age time passed) still it gets the value from cache and no header values are displayed.
