temporary page

how can i send to the browser a temporary html page from servlet invoked with post method while it is woking ?
i want that only after my servlet has finished it will response with a sendRedirect method to the client.

Is it possible that ?

Thanks.

If you only need to support Netscape then you can use
multi-part/x-mixed-replace .  It looks to me like t's not supported by
IE5.0, but I don't know if later versions will support it.

(Also, replacing "x-mixed-replace" with "mixed" may work for you.)

... the nice thing about standards is that there are so many to choose
from. ;-)

Here's a sample file.

#!/bin/sh

echo "Content-type:
multipart/x-mixed-replace;boundary=MyFavoriteBoundaryString"
echo ""
cat <<EOF
--MyFavoriteBoundaryString
Content-type: text/html

<title>Working...</title>
<body bgcolor="#f0f0f0">
<h2>Please Wait.</h2>
We are computing that answer.
</body>

--MyFavoriteBoundaryString
EOF
sleep 5
cat <<EOF
--MyFavoriteBoundaryString
Content-type: text/html

<title>Finished</title>
<body>
<h2>The answer is 42.</h2>
Now what was the question again?
</body>
--MyFavoriteBoundaryString
EOF

Put your processing in a background thread.  Put a META Refresh tag in your
HTML to refresh a monitoring servlet priodically. If the processing is not
done, the monitoring servlet returns the same refresh tag, else it
forwards/redirects to the real data you want to show.

Or you could load an applet and use it to maintain contact with the servlet
(I know it can be done, but I don't have the details.)
