"""
Sometimes in your Django model you want to raise a ``ValidationError`` in the ``save`` method, for
some reason.
This exception is not managed by Django Rest Framework because it occurs after its validation 
process. So at the end, you'll have a 500.
Correcting this is as simple as overriding the exception handler, by converting the Django
``ValidationError`` to a DRF one.

def queryset_iterator(queryset, chunksize=1000):
    '''''
    Iterate over a Django Queryset ordered by the primary key

    This method loads a maximum of chunksize (default: 1000) rows in it's
    memory at the same time while django normally would load all rows in it's
    memory. Using the iterator() method only causes it to not preload all the
    classes.

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.
