Changes between Initial Version and Version 1 of Ticket #32023, comment 3

-              initial
+              v1
 Shouldn't `request.META.__setitem__` and `request.META.__delitem__`  `del request.headers` to synchronize if the key starts with `"HTTP_"`? In the current code, if any middleware has peeked into `request.headers`, the data gets out of sync on mutation.
+{{{
+>>> from django.http import HttpRequest
+>>> req = HttpRequest()
+>>> req.META
+{}
+>>> req.headers
+{}
+>>> req.META["HTTP_X_FOO"] = 'asdf'
+>>> req.headers
+{}
+>>> req.headers
+{}
+>>> req2 = HttpRequest()
+>>> req2.META["HTTP_X_FOO"] = 'asdf'
+>>> req2.META
+{'HTTP_X_FOO': 'asdf'}
+>>> req2.headers
+{'X-Foo': 'asdf'}
+>>> del req2.META["HTTP_X_FOO"]
+>>> req2.headers
+{'X-Foo': 'asdf'}
+}}}
