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 sP t t| ��� t� | _|d k r>t|t�r4| �|� n | �|� |rL| �|� 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 |�� S )N)r �lower)r r" �valr r r r- � s zHTTPHeaderDict.__setitem__c C s | j |�� }d�|dd � �S )Nz, r )r r> �join)r r" r? r r r r$ � s zHTTPHeaderDict.__getitem__c C s | j |�� = d S )N)r r> )r r" r r r r. � s zHTTPHeaderDict.__delitem__c C s |� � | jkS )N)r> r )r r" r r r � __contains__� s zHTTPHeaderDict.__contains__c C s^ t |t�st|d�sdS t |t| ��s2t| �|�}tdd� | �� D ��tdd� |�� D ��kS )Nr5 Fc s s | ]\}}|� � |fV qd S )N)r> )�.0�k�vr r r � <genexpr>� s z(HTTPHeaderDict.__eq__.<locals>.<genexpr>c s s | ]\}}|� � |fV qd 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 | � |� 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 �� D ]}|d V q W d S )Nr )r r4 )r �valsr r r r1 � s zHTTPHeaderDict.__iter__c C s< y | | }W n t k r, || jkr(� |S X | |= |S dS )z�D.pop(k[,d]) -> v, remove specified key and return the corresponding value.
