Description Stefan Eissing 2002-12-16 14:35:29 UTC 
When sending a request with multiple defined headers like:

Some-Header: first
Some-Header: second
Some-Header: third, fourth

Only the first header line is echoed back in the response.

The implementation of doTrace() is in javax.servlet.http.HttpServlet and is 
outside of the control of the tomcat team.

The problem is that the implementation uses getHeader() rather than getHeaders
()

If this is a problem for you, your best bet is to override the doTrace() 
method in your servlet. As a starter the javax.servlet.http.HttpServlet 
impementation is available from
