What is sb protocol and how is works internally?
<p>I have configured a notification hub using Azure portal for implementation of push notifications for mobile apps. On navigating to the Access Policies section, I see couple of policies with names: DefaultListenSharedAccessSignature and DefaultFullSharedAccessSignature as shown in the below diagram. Both the policy names contain connection string. One of the connection string is as follows:</p>

<p>Endpoint=sb://expedia.servicebus.windows.net/;SharedAccessKeyName=DefaultFullSharedAccessSignature;SharedAccessKey=JnVgQvxxxxxxxxxxxxxxxxxxxxxxxy1HgWUfUo=</p>

<p>I want to understand what is <strong>sb</strong> protocol here and want to how it works internally and does it depends on HTTPS.</p>

<p>I have to access the above endpoint from a remote server. How to consider the above while white listing the proxy rules to allow access to the above endpoint.</p>
