Hi Erik, now you have already been told, where to look in the first place.
I found Hunter's explanation of ServletResponseWrappers etc. not so easy to understand. If you have questions with this, I recommend the following message: From: Andreas Probst <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Subject: Re: Is there any way to read the response headers in a filter in Tomcat 4.0.3 ?
