Instance Attribute Details

#bridge_server ⇒ Object (readonly)

The bridge server we intend to connect to. Derived from #host

def bridge_server
  @bridge_server
end

#host ⇒ Object

The host information to set up where to listen. It’s formatted as follows: [listen.host1,listen.host2,…@]bridge.host where each of the listen.hosts is a host that this server should handle requests for and the bridge.host is the address of the bridge host itself. Note that if you’re only listening on one host and it shares its ip with the bridge server itself, you can simply give it that host (ie. pickles.oncloud.org will connect to pickles.oncloud.org to server for pickles.oncloud.org) An example of a more complicated example might be: www.blah.com,[email protected] You can also have leading wildcards in the hosts: *.blorp.com,[email protected] Or more concisely (*. matches subdomains, *blah matches *.blah and blah): *[email protected] Or yet more concisely (without an @, wildcards are removed to find the address): *blorp.com And of course, to match everything on a bridge server: *@blorp.com
