(just to clarify, I meant an OpenerDirector instance, not the class

No, it does stop them being sent.  Perhaps you mutated the base class
.addheaders by mistake (using .append(("User-agent", "blah")), for
example)?  Don't do that!  Mutating class attributes is a bad idea.

No need to assure me of *that* <wink>.  You can call a base class
constructor directly, you know.  And clobbering the base class'
constructor is another very bad idea.
