On Google's app engine (GAE), how can my server tell if it's the default version?

Question

On my Google AppEngine (GAE) server, I'd like to do something like this:

if (thisIsTheDefaultServer)
{
    // behave normally
}
else
{
    // Accept special test-commands, give extra output, etc.
}

is there a way for the server code to determine if it's the current default version?

Thanks!

There's not currently any way to do this, but you might want to reconsider your requirements. Two alternatives spring to mind:

1. Switch on the hostname: If it's the bare appspot name or a custom domain name, you're serving as the default version. If it's a version.app.appspot.com name, you may or may not be the default version, but should probably enable the different behavior anyway.
2. Enable the extra behavior based on whether the user is logged in as an admin or not. This is probably a better idea all around: It makes it easier to debug your production app, and means regular users can't find the alternate version and see stuff they shouldn't.
