12544	Bogus If-Modified-Since header causes 500 in django.views.static.serve	Antti Kaihola	nobody	"Every now and then I get requests with a bogus `If-Modified-Since` header like
{{{
If-Modified-Since: Fri, 34 Feb 3118 24:34:19 GMT
}}}

These cause a server error.

Since invalid dates are most certainly only used by malicious clients, it would probably be safe to respond with a ""not modified"" HTTP response."		closed	HTTP handling	dev		fixed	static		Accepted	1	0	0	1	0	0
