title: Use firebase cloud function to send POST request to non-google server
body: <p>I was wondering if its possible to use a firebase cloud function to send a post request to a non-google server (from what I can find I need to be on the blaze plan in order to interact with non google servers)</p>
  
  <p>Basically I want to POST to an external server running on an arduino whenever a value is added to my database.</p>
  
  <p>I have looked through the docs and found examples of having a cloud function respond to an HTTP post request (HTTP cloud functions) but can't seem to find any examples of posting to an external server. Is this possible?</p>
