I think we should rename isSameOrigin to isAllowedOrigin and move this logic there.

Also, please process environmental variables in the root scope, near the top of the file, rather than within the middleware itself. At the moment this replace/split has to be executed for every single request which is an unnecessary cost.

sessionMiddleware(req, res, next);
} else {
next();
