> I noticed when running SolrJ app with a profiler that there is some time
> spent in {{{}InMemoryCookieStore.get(URI){}}}. It's not a lot, but it's
> something and it has a lock so I'm guessing it may be worse with high number
> of threads.
> Searching in the code, I can see the Kerberos auth seems to use cookies, but
> I can't see anything else. I'm thinking we should at least make the
> CookieStore optional, or maybe just enable it for Kerberos, unless I'm
> missing something
