Not sure what else you need. Code is sample code supposed create caching headers to lessen HTTP server load. Server is Apache2 on localhost, Browser is IE6. After loading the page, then clicking 'reload' the issue appears. The problem only appears with direct connection, when going why proxy it doesn't happen.

The error only happens the second time. Headers sent by IE first time are: GET /caching.php HTTP/1.1 Accept: */* Accept-Language: en-us,de;q=0.5 Accept-Encoding: gzip, deflate If-Modified-Since: Thu, 05 Aug 2004 12:57:27 GMT; length=0 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Host: supportweb.dyndns.org Connection: Keep-Alive Cookie: ZDEDebuggerPresent=php,phtml,php3 Answer: HTTP/1.0 200 OK Date: Thu, 05 Aug 2004 12:57:27 GMT Server: Apache/2.0.50 (Win32) mod_ssl/2.0.50 OpenSSL/0.9.7d PHP/5.0.0 X-Powered-By: PHP/5.0.0 Set-Cookie: ZDEDebuggerPresent=php,phtml,php3 pragma: cache, no-cache cache-control: public, no-store, no-cache, must-revalidate, post-check=0, pre-check=0 last-modified: Thursday, 05-Aug-04 12:57:27 GMT Content-Encoding: gzip Content-Length: 20 Connection: close Content-Type: text/html; charset=ISO-8859-1 Headers send by IE second time are: GET /caching.php HTTP/1.1 Accept: */* Accept-Language: en-us,de;q=0.5 Accept-Encoding: gzip, deflate If-Modified-Since: Thu, 05 Aug 2004 12:57:27 GMT; length=0 User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Host: supportweb.dyndns.org Connection: Keep-Alive Cookie: ZDEDebuggerPresent=php,phtml,php3 Answer: HTTP/1.0 200 OK Date: Thu, 05 Aug 2004 12:57:29 GMT Server: Apache/2.0.50 (Win32) mod_ssl/2.0.50 OpenSSL/0.9.7d PHP/5.0.0 X-Powered-By: PHP/5.0.0 Set-Cookie: ZDEDebuggerPresent=php,phtml,php3 Content-Encoding: gzip Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-Length: 197 Connection: close Content-Type: text/html; charset=ISO-8859-1
