Subject RE: Removal of headers in HttpServletResponse object
Date Fri, 21 Jul 2006 09:53:30 GMT
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 ?

Geir :-)

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 :-)
