Hello, we want to use the presence module of openser in combination with eyebeam pa mode. In order to save bandwith, we want the clients to subscribe in an intervall of 1 hour. At the same time, we want to detect almost instantly when I client timeouts, i.e. has a network failure. Is there any way I can detect client timeouts rather fast other than reducing the max_expires value, which also affects the SUBSCRIBE timeout and therefore increasing the network utiliztion again? openser version is 1.2.0-dev12-notls , eyebeam version is 1.5.10.2 build 33793 Thanks in advance for your help Schnell und einfach ohne Anschlusswechsel zur Lycos DSL Flatrate wechseln und 3 Monate kostenlos ab effektiven 5,21 EUR pro Monat im ersten Jahr surfen. http://www.lycos.de/startseite/online/dsl/index.html?prod=DSL&trackingI…
