4.5.2 Table Object (mp_table)

class `table`([mapping-or-sequence])
  Returns a new empty object of type `mp_table`. See Section 4.5.2 for description of the table object. The mapping-or-sequence will be used to provide initial values for the table.

  The table object is a wrapper around the Apache APR table. The table object behaves very much like a dictionary (including the Python 2.2 features such as support of the `in` operator, etc.), with the following differences:

  - Both keys and values must be strings.
  - Key lookups are case-insensitive.
  - Duplicate keys are allowed (see `add()` below). When there is more than one value for a key, a subscript operation returns a list.

  Much of the information that Apache uses is stored in tables. For example, `req.headers_in` and `req.headers_out`.

  All the tables that mod_python provides inside the request object are actual mappings to the Apache structures, so changing the Python table also changes the underlying Apache table.

  In addition to normal dictionary-like behavior, the table object also has the following method:

  `add`(key, val)
    `add()` allows for creating duplicate keys, which is useful when multiple headers, such as `Set-Cookie:` are required.
