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 2616. 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' If you want to access the raw headers with their original casing for debugging purposes you can access the private ``._data`` attribute which is a normal python ``dict`` that maps the case-insensitive key to a list of tuples stored as (case-sensitive-original-name, value). Using the structure from above as our example: >>> headers._data {'set-cookie': [('Set-Cookie', 'foo=bar'), ('set-cookie', 'baz=quxx')], 'content-length': [('content-length', '7')]} Nc K s2 i | _ | d k r i } n | j | | � d S)N)�_data�update)r �headers�kwargsr r r r � s zHTTPHeaderDict.__init__c C s, | j j | j � g � j | | f � d S)z�Adds a (name, value) pair, doesn't overwrite the value if it already exists. >>> headers = HTTPHeaderDict(foo='bar') >>> headers.add('Foo', 'baz') >>> headers['foo'] 'bar, baz' N)r3 � setdefault�lower�append)r r r& r r r �add� s zHTTPHeaderDict.addc C s! | | k r | | j d � Sg S)zmReturns a list of all the values for the named field.
