Not necessarily the rewriter as it's currently written. I was looking into how I can modify content while it's being generated and I had forgotten about the fact that we now support asynchronous servlets and filters. I haven't dived to far into this yet but the basic idea would be
# determine that a request would be handled by a rewriter # pass the request off to a separate thread for processing # process the data that is being written to the output and run it through the rewriter and push it out the other side. If you've worked with asynchronous servlets, am I missing any important concepts here? - Jason
