Nice. I'm just now working on something that I wanted to use the idea of "progressive enhancement" and went about this a slightly different way. But this is nice.

Is the "HTTP_X_REQUESTED_WITH" header common in all browsers?

Sorry, I suppose the header would have to be common in the Javascript library you use since it would be sending headers. Thanks.

I figured out that you can just use request,is_ajax in the template without using any middleware:

{% if request.is_ajax == True %} ajax specific html. {% endif %}
