Thanks for your reply.
I am running Tomcat 5.0.28 which is the default for the Netbeans IDE which
I am using. I develop the classes in the IDE, launch tomcat from the IDE,
then run the test from a command prompt.
I will run your code and see if it gives me clean results. It looks like
you have distilled the essence of the problem.
Regards,
Bill

Hi Willie,
I have tried to re-produce your problem, but my test-case does not fail.
I'm trying with tomcat-5.0.28. My test codes are appending:
SampleServlet.java
SampleServletTest.java
The SampleServlet is mapped to /refersample in my case.

In my code, corresponds to SampleServlet#processRequest().
At this method, the request is dispatched to "/refersample",
i.e. I'm expecting SampleServlet#doGet() will be called.

In my code, corresponds to SampleServlet#doGet(). At this point,
request.getHeader("Referer") of my code has non-null value,
"/test.jsp", and of cource, 302 response code is received at
SampleServletTest#endReferer().
warmstr2> The String strRefUrl is set to null so the sendRedirect of course
fails.
How could we re-produce the problem?
