| The Request.headers dictionary is not a documented interface. It should |
| stay that way, because the complete set of headers are only accessible |
| through the .get_header(), .has_header(), .header_items() interface. |
| However, .headers pre-dates those methods, and so real code will be using |
| the dictionary. |
| |
| The introduction in 2.4 of those methods was a mistake for the same reason: |
| code that previously saw all (urllib2 user)-provided headers in .headers |
| now sees only a subset (and the function interface is ugly and incomplete). |
| A better change would have been to replace .headers dict with a dict |
| subclass (or UserDict.DictMixin instance?) that preserved the .headers |
| interface and also provided access to the "unredirected" headers. It's |
| probably too late to fix that, though. |
