Question

How to disable browser cache when logout takes place. I used:

<meta http-equiv="cache-control" content="no-cache"> <!-- tells browser not to cache -->
<meta http-equiv="expires" content="0"> <!-- says that the cache expires 'now' -->
<meta http-equiv="pragma" content="no-cache"> <!-- says not to use cached stuff, if there is any -->

But still I am getting the previous page , when I click logout.

This should work on most browsers, but to prevent Firefox from caching, you need an additional two headers Cache-Control=no-store and Cache-Control=must-revalidate. Therefore try:

<meta http-equiv="expires" content="0">
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="cache-control" content="no-store">
<meta http-equiv="cache-control" content="must-revalidate">

See how can i prevent firefox caching.
