> AcceptHeaderDelete.fromString() is called for every invocation.  This drives calls to string splits and some regex tools that start to show up in profiles as taking up a notable amount of time.  Since the content for the Accept headers will remain within a fairly bounded set, we can cache the parsed content and improve performance.
> Here's a patch with a simple solution.  Really I think there's a better way to do this.  Presumably, there are other headers where the same thing applies.  We can handle those on an individual basis or we can come up with something more generic that can be used by all HeaderDelegates.
