> 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.
