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 sPtt|jt|_|dk r>t|tr4|j|n |j||rL|j|dS)N)superrrrr isinstance _copy_fromextend)rheaderskwargs) __class__rrrs   zHTTPHeaderDict.__init__cCs ||g|j|j<|j|jS)N)rlower)rr!valrrrr)szHTTPHeaderDict.__setitem__cCs |j|j}dj|ddS)Nz, r)rr:join)rr!r;rrrr#szHTTPHeaderDict.__getitem__cCs|j|j=dS)N)rr:)rr!rrrr*szHTTPHeaderDict.__delitem__cCs|j|jkS)N)r:r)rr!rrr __contains__szHTTPHeaderDict.__contains__cCsbt|t rt|d rdSt|t|s6t||}tdd|jDtdd|jDkS)Nr1Fcss|]\}}|j|fVqdS)N)r:).0kvrrr sz(HTTPHeaderDict.__eq__..css|]\}}|j|fVqdS)N)r:)r>r?r@rrrrAs)r4rhasattrtypedict itermerged)rotherrrr__eq__s  zHTTPHeaderDict.__eq__cCs |j| S)N)rG)rrFrrr__ne__szHTTPHeaderDict.__ne__cCs t|jS)N)r&r)rrrrr+szHTTPHeaderDict.__len__ccs"x|jjD]}|dVq WdS)Nr)rr0)rvalsrrrr-szHTTPHeaderDict.__iter__c Cs<y ||}Wn tk r,||jkr(|SX||=|SdS)zD.pop(k[,d]) -> v, remove specified key and return the corresponding value.
