Subject Re: Is there a problem with AsyncHttpClient connection reuse?
Date Mon, 14 Jan 2008 22:17:27 GMT
Yes, if you used a different configuration for the SSL, then it would be
another issue.
The questions are:
- Do we want to even allow an option for using a shared connection cache?
The benefit of a shared connection cache is ... just that; connection reuse
will be maximized for the given process.  However, the drawback is that you
may run into unexpected socket configuration/SSL configuration behavior when
you hand the connections to a different client instance.
- If we do allow it, what should be the default?
I think *not* sharing the connection cache might be a better default
