Not exactly as written, but close enough to get me working.  At one 
point the following code is executed, turning the value into a string to 
be  "title"d next time it is called:

    name = name.title()


So, I worked around it with the following class, adapted from yours:

    class CaseSensitiveHeader(object):
         def __init__(self, name):
             self.name = name

         def capitalize(self):
             return self

         def title(self):
             return self

         def lower(self):
             return self.name

         def encode(self, encoding):
    return self.name.encode(encoding)


With that, I am now able to post a case sensitive HTTP header.
