An unreachable network will often hang the client JVM. The socket timeout only applies to "normal" communication errors...if you'll allow that kind of term. We've done extensive testing of network communications in this kind of failure use case. I do not believe there is a way for HttpClient to work around this because the hang is deep inside the JVM native code.
There is a method in InetAddress (isReachable(long ms)) to test if a host is reachable. But, even that will provide varying and misleading results. If you expect to encounter this often the only way to work around it is to execute this in a daemon thread and abandon the thread if it does not complete within the defined timeout period. ...Pete Starbucks Coffee Co. - MS IT-5 2401 Utah Ave S Seattle, WA. 98134 (w) 206-318-5933 -----Original Message----- From: Vitaly Baranovsky [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 15, 2007 7:57 AM To: [email protected] Subject: Why connection timeouts doesn't works? Good day! Connection timeouts of httpClient in my program doesn't works. I set timeout to 10 000 milliseconds, but my program waits for about 65 seconds before answering.
