This module contains functions for building an HTTP application framework: any one, not just one whose name starts with "Ch". ;) If you reference any modules from some popular framework inside *this* module, FuManChu will personally hang you up by your thumbs and submit you to a public caning. � N)� b2a_base64)� decode_header)�BaseHTTPRequestHandler)� unquote_plus)�ntob�ntou� �� parse_header)zInternal Server Errorz^The server encountered an unexpected condition which prevented it from fulfilling the request.i� )zService UnavailablezqThe server is currently unable to handle the request due to a temporary overloading or maintenance of the server.i� T)�usegmtc G �8 d� dd� | D ��}d|v r|�dd�}d|v s|pdS )z�Return the given path \*atoms, joined into a single URL.

Each (start, stop) tuple will be composed of two ints, which are suitable for use in a slicing operation. That is, the header "Range: bytes=3-6", if applied against a Python string, is requesting resource[3:7]. This function will return the list [(3, 7)]. If this function returns an empty list, you should return HTTP 416.
