Redirect/Forward Not working for multipart/form-data - worka

[jimotte]

I have a jsp that posts to a control servlet a file to be uploaded- content type multipart/form-data- the problem is that if it throws an error in my request processing I want to redirect to an error.jsp. This works fine in Netscape but IE completely chokes. Even if I have a simple
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{

response.sendRedirect("JSP/error.jsp");
}

IE will not redirect it!!
The only away around this I have found is to actually read in the whole InputStream and then I can redirect- IE seems to wait for this reading before I can redirect- RequestDispatcher().forward is the same-
My ?:
Does anyone know how I can redirect or forward the response without reading in the whole uploaded file (whih I'm trying to avoid)?????

Thanx
Jim

Without testing this myself, have you tried
InputStream.close() or does lead IE to assume the
page is broken?

Yes, Adrian- I tried that too- but to no avail- if the stream is closed before it is completely read it will still not redirect in IE.
The only times it redirects without reading the stream completely is when the uploaded file is very small- I think IE has opened up a socket connection and until all the packets have arrived the browser will not close the connection. So when there is a redirect command with outstanding packets still there- it does redirect as the browser still has the connection open.
Perhaps if there were a way of closing the connection (without messing with the innards of Tomcat preferably)- that might work....This of course is speculation...
It seems like there must be some way without reading in a potentially large file....

meant to say (from last post):

I don't think there's much you can do if the browser
has wont read the response until the request has
been completed :-(
