I get to that page below fine. It's an intranet site behind a
firewall so I dont' think you'll be able to get there.
I'm suspecting the problem has something to do possibly with sending
multipart/form-data in the request object? Does this possibly have to
be handled differently in order to enable a redirect in a servlet?
The reason I suspsect this is part of the problem is I stripped out
all the code and just put a simple redirect in the try block and when
I call the servlet it still will not redict. However if I go to the
form page that calls this servlet and I remove the <form
ENCTYPE="multipart/form-data" action=...>, the servlet will redirect
fine. So possibly when sending multipart/form-data the servlet is
required to handle it differently???
Is anyone familiar with this problem? (By the way the code works fine
if I jack up the file size allowed and make sure the file being
uploaded is below that size. It's set to 1Meg now for debugging. I'd
like to be able to send a redirect or out.prints that are cleaner if
the user happens to upload a file that is too large. Right now I am
unable to do this).
Thanks again for any help.
