Will It Connect?

Sometimes, you just want to know if you can reach your thing (service really) from Cloud Foundry. Is there a proxy in the way, is there an app security group, the dreaded firewall of doom or is it your code? Will It Connect takes a url or hostname and a port or an ip and a port and tries to make a
connection from inside Cloud Foundry. If your destination allows us to open a socket or responds to a GET request on the URL, we report success, if not, we fail. Deploy it to the same space you intend to run your app and you can test the exact environment! The original usecase was designed with non http connections in mind, so we don't make any assumptions about protocol unless you provide a url (i.e. something that starts with http:// or https://. We simply open a socket connection to the host and port. If you provide a URL we make a GET request, including SSL handshake if required.
