GEO site health checking has been expanded to include the HTTP HEAD method. This can be useful for many different application types. The following configuration options are supported:

  • Specify the name and content of a specific header to provide to the application.
  • Up to 4 custom headers can be defined per GEO Site.
  • The status of the last health check performed is reflected in the UI and log.
  • Return codes of 200-299, 301, 302, and 401 are interpreted to mean the server is healthy.

The following example shows how to configure an HTTP HEAD check to authenticate to the site using basic authentication via the Authorization header. The header value is “Basic”, followed by a space, followed by a base64-encoded string.
