Is there a way to disable the browser cache for a single page?


For a small intranet site, I have a dynamic (includes AJAX) page that is being cached incorrectly by Firefox. Is there a way to disable browser caching for a single page?

Here's the setup I'm using:

  • Apache under XAMPP, running on a Windows server
  • PHP


The content that I'm primarily concerned about is page text and the default options in some <select>s. So I can't just add random numbers to the end of some image URLs, for example.


I followed the suggestions I've gotten so far:

  • I'm sending nocache headers (see below)
  • I'm including a timestamp URL parameter and redirecting to a new one if the page is reloaded after 2 seconds, like this:

    $timestamp = $_GET['timestamp'];
    if ((time()-$timestamp) > 2) {

Now Firebug shows that the headers specify no cache, but the problem persists. Here are the response headers for the page:

Add current timestamp as parameter of url, e.g.
