Problem of reload with Firefox on back button

Dear all,
I could see a problem with FireFox when doing a back in browse history: the page is not reloaded, on the contrary: it is loaded  from browser cache.
I found on Internet that we should have more headers in the page to force FF to reload the page even with a back in history.
So in display.function.php file, instead of :

/**
 * Set page not to use the cache
 **/
function header_nocache() {

   header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
   header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date du passe
}

We should have

/**
 * Set page not to use the cache
 **/
function header_nocache() {

   header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); // HTTP/1.1
   header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date du passe
}

I made a test, and this really forces FF to reload the page even when doing a back in history.
Could it be possible to add this in future releases of GLPI?
Thank you,
Regards,
Tomolimo

Re: Problem of reload with Firefox on back button

It seems that there is the same problem with IE9, and it's ok with the same solution.
Who can confirm?
