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.

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

I've been having problems with Internet Explorer caching php

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. You can check this using:
