note 56655 added to ref.image

Need help desperately :( I am not able to change my last modified header. This seems to be my BIG problem. I made a single line php file and executed. <?php header("Last-Modified: Sun, 11 Sep 2005 15:34:36 GMT"); ?> As i inspected in the telnet window, the Server still said the current GMT time. I am using Apache/2.0.53 (Win32) PHP/5.0.4 The response was: HTTP/1.1 200 OK Date: Sun, 11 Sep 2005 16:45:46 GMT Server: Apache/2.0.53 (Win32) PHP/5.0.4 X-Powered-By: PHP/5.0.4 Content-Length: 0 Connection: close Content-Type: text/html; charset=ISO-8859-1 There was no Last-Modified header at all. The same way the "ETag: " header also is not working for me :( Because of this I am not able to implement cache techniques. What could be the problem?
