Must not contain multiple field names when compared case-insensitively. :param kwargs: Additional field-value pairs to pass in to ``dict.update``. A ``dict`` like container for storing HTTP Headers. Field names are stored and compared case-insensitively in compliance with RFC 7230. Iteration provides the first case-sensitive key seen for each case-insensitive pair. Using ``__setitem__`` syntax overwrites fields that compare equal case-insensitively in order to maintain ``dict``'s api. For fields that compare equal, instead create a new ``HTTPHeaderDict`` and use ``.add`` in a loop. If multiple fields that are equal case-insensitively are passed to the constructor or ``.update``, the behavior is undefined and some will be lost. >>> headers = HTTPHeaderDict() >>> headers.add('Set-Cookie', 'foo=bar') >>> headers.add('set-cookie', 'baz=quxx') >>> headers['content-length'] = '7' >>> headers['SET-cookie'] 'foo=bar, baz=quxx' >>> headers['Content-Length'] '7' Nc sn t t | � j � t � | _ | d k rW t | t � rJ | j | � n | j | � | rj | j | � d S)N)�superr r r r � isinstance� _copy_from�extend)r �headers�kwargs)� __class__r r r � s zHTTPHeaderDict.__init__c C s* | | g | j | j � <| j | j � S)N)r �lower)r r" �valr r r r- � s zHTTPHeaderDict.__setitem__c C s* | j | j � } d j | d d � � S)Nz, r )r r> �join)r r" r? r r r r$ � s zHTTPHeaderDict.__getitem__c C s | j | j � =d S)N)r r> )r r" r r r r. � s zHTTPHeaderDict.__delitem__c C s | j � | j k S)N)r> r )r r" r r r � __contains__� s zHTTPHeaderDict.__contains__c C s� t | t � r$ t | d � r$ d St | t | � � sK t | � | � } t d d � | j � D� � t d d � | j � D� � k S)Nr5 Fc s s' | ] \ } } | j � | f Vq d S)N)r> )�.0�k�vr r r � <genexpr>� s z(HTTPHeaderDict.__eq__.<locals>.<genexpr>c s s' | ] \ } } | j � | f Vq d S)N)r> )rB rC rD r r r rE � s )r8 r �hasattr�type�dict� itermerged)r �otherr r r �__eq__� s zHTTPHeaderDict.__eq__c C s | j | � S)N)rK )r rJ r r r �__ne__� s zHTTPHeaderDict.__ne__c C s t | j � S)N)r( r )r r r r r/ � s zHTTPHeaderDict.__len__c c s' x | j j � D] } | d Vq Wd S)Nr )r r4 )r �valsr r r r1 � s zHTTPHeaderDict.__iter__c C sH y | | } Wn( t k r8 | | j k r0 � | SYn X| | =| Sd S)z�D.pop(k[,d]) -> v, remove specified key and return the corresponding value.
