Thanks.  For some reason, I couldn't find any references with Ctrl-F on the review page.

Given that it extends ContextualHttpServletRequest, I think Request should form part of the class name.  What about RateLimitingWrappedRequest, or RateLimitingDelegatingRequest, given that it doesn't really do any processing itself?

Also, the class needs a javadoc to explain about the Seam context.
