Re: Internet Explorer Caching

I had used something similar in another iteration of trying to fix the caching problem in IE. I tried these lines again, and they don't work. It is only IE that is caching. Charlene Satyam wrote:

I'm sending these headers:

      header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1
      header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past

I don't remember where I took them from, but they are working fine for me.

I've been having problems with Internet Explorer caching php programs. I'm using the following code:

       header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
       header("Pragma", "no-cache");
       header("Expires", "-1");

And it used to work, but now, according to Windows Explorer its giving it 3 hours to expire.

Are you sure? By default PHP pages/scripts don't send any caching headers and hence don't get cached.
