Disable ssl redirect for specific handler

I am using Django application hosted on Google App engine(GAE). GAE sends ‘/_ah/start’ request to start the instance if no instance is running to serve the actual user request. In my case I have enabled SSL redirect ‘SECURE_SSL_REDIRECT = True’ which returns response status as 301. But GAE requires 2xx or 404 response. So I want to exclude this ‘/_ah/start’ to be excluded from default redirect.
Any suggestions how can I do it?
