Now it's `false`: https://github.com/apache/httpcomponents-client/blob/ffe4a05f4faf3706a41ff660bcb3474c6b5101a3/httpclient5/src/main/java/org/apache/hc/client5/http/ssl/AbstractClientTlsStrategy.java#L208 This was deliberately changed in this commit: https://github.com/apache/httpcomponents-client/commit/ee0a102104d03a8d1cfe18e571d179c41242182c On Thu, May 29, 2025 at 6:08 PM Ryan Schmitt <rschm...@apache.org> wrote: > > I've been debugging a load test regression, which turned out to be > caused by a client instance leak.
