with a redirect nothing should be written to the stream i believe.

In my AddResponseHeaders filter (it's in the stack-trace) my code
reads:
HttpServletResponse response = (HttpServletResponse) servletResponse;
// set the provided HTTP response parameters
for (Enumeration e=config.getInitParameterNames();
e.hasMoreElements();)
{
String headerName = (String) e.nextElement();
response.addHeader(headerName,
config.getInitParameter(headerName));
}
chain.doFilter(servletRequest, servletResponse);
so really all I am doing is setting response headers, why would
this cause problems for redirect? Is this normal?

I added some more info (the redirect url) so that you can see which
urls are causing these problems.

This does not occur on a regular basis but if it's a bug, it
would be nice to be able to track it down and fix it.
