13755	HttpRequest.is_ajax() should be used together with vary_on_headers('HTTP_X_REQUESTED_WITH')	Miloslav Pojman	nobody	"Sending different response depending on HttpRequest.is_ajax() breaks Django cache middleware (an possibly others).

Easy fix is use vary_on_headers('HTTP_X_REQUESTED_WITH') decorator and I think this practice should be documented near is_ajax method http://docs.djangoproject.com/en/1.2/ref/request-response/#django.http.HttpRequest.is_ajax"	Bug	closed	Documentation	1.0	Normal	fixed		miloslav.pojman@…	Ready for checkin	1	0	0	0	0	0
