I now have two win7s in a local area network called A and B. A now can run shiny app, and it shows that it listen 192.168.1.100:6271. And A can visite the app in A's own chrome using 192.168.1.100:6271. Then I want to B to visite A's shiny app. I type 192.168.1.100:6271 in chrome, but it doesn't work. B also has a IP like 192.168.1. 102. I know little about web, but i can turn on my IIS in A, then B can visite 192.168.1.100£¬ but for a application, i don't know what to do. Is my question clear ?
