title: How to define a static url in app.yaml "Google App Engine"?
body: <p>I am trying to make an ajax call in my project to the file in the root directory named <code>abc.php</code>. This ajax call gets succeed when I try it on local server. But on server it gives <code>500 server error</code>.</p>
  
  <p>I think the problem is that I need to set the static url in <code>app.yaml</code>. According to the given <a href="https://cloud.google.com/appengine/docs/standard/php/config/appref#handlers_element" rel="nofollow noreferrer">doc</a>. I implemented the following code:</p>
  
  <pre><code>handlers:
  
  - url: /abc
    script: abc.php
  
  # Serve images as static resources.
  - url: /(.+\.(gif|png|jpg|jpeg|css|js|pdf|woff|woff2|eot|svg|ttf|ico))$
    static_files: \1
    upload: .+\.(gif|png|jpg|jpeg|css|js|pdf|woff|woff2|eot|svg|ttf|ico)$
    application_readable: true
  
  - url: /.*
    script: index.php
  </code></pre>
  
  <p>But I am still not able to access <code>abc</code> url on server.
  Can anyone please tell what is wrong with it?</p>
