Thanks again for quick reply, I´ll investigate more into using the SSE client. At the moment i´m playing around with zurl/webhooks. Its working great with python. However using java i get into a problem with the ipc protocol. I tried to change the zurl.conf configuration from something like ipc://usr/local/var/run/pushpin/pushpin-zurl-in to tcp://localhost:10001. It seems like the zurl.conf file is overwritten when i start pushpin. Googling the problem reveals that java does not support "unix domain socket". So it is a way to change the config in zurl.conf?
