+endpoints matching the following regular expressions::

+This "stub" presence handler will pass through ``GET`` request but make the

 It will proxy any requests it cannot handle to the main synapse instance. It
 must therefore be configured with the location of the main instance, via
 the ``worker_main_http_uri`` setting in the frontend_proxy worker configuration
