HTTP header incorrectly displaying in IE6

This code works fine in Internet Explorer 5 for all versions, but is not working on IE6. When I run the page on an IE6 browser, it displays the HTTP header as text in the browser.

HTTP/1.1 200 OK
Date: Tue, 04 Feb 2003 19:42:28 GMT
Server: Apache/1.3.20 (Win32) mod_jk
Pragma: No-cache
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Cache-Control: private
Set-Cookie: One=0;Path=/
Set-Cookie: Two=0;Path=/
Servlet-Engine: Tomcat Web Server/3.2.3 (JSP 1.1; Servlet 2.2; Java 1.3.1;
Windows 2000 5.0 x86; java.vendor=Sun Microsystems Inc.)
Keep-Alive: timeout=15, max=97
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html; charset=utf-8 e05
I am using cookies in my JSP pages, and I have set headers as following:
response.setHeader("Pragma", "No-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "private");
I am setting cookies as follows:
Cookie ckiOne = new Cookie("One", java.lang.String.valueOf(m_iOne));
ckiOne.setPath("/");
response.addCookie(ckiOne);
Cookie ckiTwo = new Cookie("Two", java.lang.String.valueOf(m_iTwo));
ckiTwo.setPath("/");
response.addCookie(Two);
Any help in this regard would be great. I have set the browser to "Accept all cookies".

Your response is the Status-line and response header of the HTTP message that your browser received. HTTP uses text headers to pass information about request and response messages. Each header consists of a list of unordered fields containing a field name and a field value delimited by a colon and a space. The Status-Line consists of the HTTP-protocol version followed by a status code and an a status phrase. The first digit of the status code defines the response class.

Your JSP code is explicitly trying to set the HTTP headers. Since the servlet compiled from your JSP handles this automatically any attempts to manually set them could result in them being handled as page content.

Try removing the "setHeader" lines from your code.
