title: Webhooks subscribe/publish with queue
body: <p>I am trying to implement application on proxy server which will provide instant notifications based on web hooks.</p>
  
  <p>How it is going to work is:
  Client sends a subscribe http request to server providing callback url 
  something like: </p>
  
  <pre><code>http://example.com/subscribe?callbackurl=&amp;other_parameters=
  </code></pre>
  
  <p>That request will be saved. Later (when event within server occurs) we are going to send notification to that callback url containing data.</p>
  
  <p>I can implement this by myself, but simple app right now is not solution because it needs to handle huge traffic (like 1 - 2 millions responses per day) without losing requests and without choking.</p>
  
  <p>Because of that, I am wondering is there any kind of open source solution with full stack implementation you can suggest (or solution which i need to pay but possible to configure and host on my own server) which have things i mentioned above and which scales really good when we are taking about huge traffic.</p>
  
  <p>When i say full stack implementation, I am referring on software which i can install on my server, then i can publish a message to a queue or something like that from script within the server, and then stack will to the rest (will queue the message, will check subscribers, will publish/send response to callback, handling huge traffic and a lot of requests internally).</p>
  
  <p>What i want is something like <a href="http://www.iron.io/" rel="nofollow">http://www.iron.io/</a> but on my own server. iron.io seems to be great solution (where you can configure how much retries you want etc..)  but it is cloud based and i am not able to use solution like that.</p>
  
  <p>Am i able to use <a href="http://resthooks.org/" rel="nofollow">http://resthooks.org/</a> and configure/implement my own system for queuing? Anyone tried it before, can you please share your experience?</p>
  
  <p>Thank you.</p>

  <p><strong>EDIT:</strong> Even i thought that subscribe/response services with full stack are quite popular after detailed research i implemented my own solution.</p>
