Subject Re: Possible bug in RequestDispatcher?
Date Mon, 04 Nov 2002 19:53:06 GMT
OK, that clarifies things a little bit.  If the problem isn't with 
RequestDispatcher, I am even more puzzled.  I have narrowed the problem 
down to a particular use case:

I have a single filter that calls 

response) in the absence of a particular session variable on the request.

This filter is mapped to /* and I have a single servlet mapped to /Display

Pointing my browser at /<webapp>/Display : things work as expected.
Pointing my browser at /<webapp>/ : things work as expected
Pointing my browser at /<webapp>/staticfile.html : problem.

View Source in my browser shows this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

    <form action="j_security_check" method="POST">

That is the beginning of the html file I am trying to forward() to.

It seems like my HttpServletResponse's OutputStream is getting closed 
prematurely in the exact same place in my forwarded file.

So what could it be?!
