Re: Servlets, send redirect and request scope

How would I do that. I know about filters. But what about in this
context.

Would I use the redirect to hit a 'filter'.

Yes. For example, you might use something like this:

1. Set a session attribute before you redirect containing the desired
request attributes and parameters.

2. Install a filter that intercepts all requests.

- If the session attribute doesn't exist, then just pass the request
along the chain without doing anything.

- If the session attribute does exist, then build a wrapped request
that returns the desired attributes and parameters, and pass that
along the chain.
