 SDK autoloading happens as part of the composer autoloader.
 
+### Excluded URLs
+
+You can disable SDK autoloading if the request URL matches a regular expression.
+Matching an excluded URL prevents any telemetry from being generated or
+exported. You can use this feature in a shared-nothing PHP runtime like Apache
+or NGINX, for requests such as health checks.
+
+For example, the following configuration turns off telemetry for requests such
