Could you please build HttpClient from my private experimental branch at github and re-run your tests? https://github.com/ok2c/httpclient/tree/dyn_proxies https://github.com/ok2c/httpclient/commit/246095522504ddffe07caf70db4c051fa0d31872 Cheers Oleg --------------------------------------------------------------------- To unsubscribe, e-mail: httpclient-users-unsubscr...@hc.apache.org For additional commands, e-mail: httpclient-users-h...@hc.apache.org
