title: How to make Google Apps Script execute as an user accessing it without CORS error
body: <p>I have a Google App Script deployed as a Web app that gets direction info based on query parameters via <code>DirectionFinder</code>.</p>
  <p>And there is also a front end app on a different domain that sends API requests to the Web app above.</p>
  <p>I have experimented with the deployment option and it turned out that API requests cause CORS error unless the GAS is deployed to execute as myself (NOT user accessing the web app).</p>
  <p>Is there anyway to deploy GAS to be executed as an user accessing it?</p>
  <p>Or is it safe to simple deploy it to execute as myself? (I fear that this will allow anonymous users to abuse my quotas)</p>
