You'll probably need to write your own connector!
See prepareResponse method:
http://svn.apache.org/repos/asf/tomcat/connectors/trunk/http11/src/java/org/apache/coyote/http11/Http11Processor.java
http://svn.apache.org/repos/asf/tomcat/connectors/trunk/http11/src/java/org/apache/coyote/http11/Http11AprProcessor.java
In any case, at the very least the Date header is mandatory in the
response for an HTTP/1.1 response (see rfc2616).

Hi all,
I am still struggling with the removal of header problem.
I found that the ServletResponse has a reset() method which should delete all
headers.
I thought maybe I could use this and then reconstruct the response object with
only the headers I want.
I tried to do call this method in the http servlet code itself but when the
object is returned Tomcat reconstruct the original headers before sending the
response to the client.
For this to work must the reset() method be called from a Filter or a Valve ?

Hi Martin,
Thanks for the feedback but I am afraid that the example did not really solve
my problem.
As far as I can understand your example only includes adding a header not
removing.
It also relies on the standard HttpServletResponse methods which does not
include a removeHeader method.

Geir-
I found a complete Tomcat Valve example here at
http://www.explain-it.org/mediawiki/index.php/TomcatValve
where the invoke() method would modify the outgoing response to omit the Header
..

Subject: Removal of headers in HttpServletResponse object
Hi ,
For fast prototyping and test purposes I am trying to simulate the responses of
various devices (web cameras with embedded web servers) by using Tomcat.
The problem I have is that Tomcat (5.5.17) seems to add by default the
following headers to the HTTP/1.1 200 OK response:
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=ISO-8859-1
Content-Length: 82
Date: Thu, 20 Jul 2006 09:53:33 GMT
These headers are not included by the various embedded devices I am trying to
simulate.
As the HttpServletResponse class does not have a removeHeader method (only
add... And set...) I am stuck.
I have tried to look into the use of Filters but to my understanding the Filter
also relies on the methods of HttpServletResponse for manipulation of the
response object.
Can Tomcat in any way be configured to not include the headers ?
Are there any other way to remove the headers ?
Geir :-)
